Design, Analysis, Simulation and Validation of Suspension System for an Electric All-Terrain Vehicle (ATV)

ABSTRACT: Suspension is the most vital sub-system in an automobile. Its main functions are load transfer to the wheels and protection of the driver from road shocks. The purpose of this paper is to select suitable suspension system for the front and the rear of an All-Terrain Vehicle (ATV) with rear electric drive and to thereafter design, analyze, simulate and test the suspension systems for optimum performance of the vehicle, driver safety and maximum driver comfort. The camber and caster angles, toe and the Ackermann variations were given due consideration. The stability of the vehicle was given importance and the system was designed to be durable enough to withstand shocks from the harsh terrain where ATVs are generally used. The springs were designed by calculations and the components were designed using CATIA. The components were analyzed using NASTRAN/PATRAN commercial FEA software andthe front and rear systems were simulated using Lotus software.

Design, Static and Dynamic analysis of an All-Terrain   Vehicle Chassis and Suspension System

Design, Static and Dynamic analysis of an All-Terrain Vehicle Chassis and Suspension System

The objective of the study is to design and analyze on static and dynamic failures of the chassis for All - Terrain Vehicle. Material selected for the chassis based on physical strength, cost and availability. The roll cage is designed accordingly to provide all the automotive sub-systems. A software model is prepared in Solid works software and for finite Element analysis the design is tested against all modes of failure by conducting various simulations and stress analysis with the aid of Ansys Software (14.0). Based on the result obtained from these tests the design is modified accordingly. After successfully designi ng the roll cage, it is ready for fabricated. The vehicle is required to have a combination frame and roll cage consisting of steel members. The ATV should run continuously for four hours in various terrains, especially loose and uneven roads with high bumps, deeper potholes and muddy terrain on the surface. The input from the road surface to the ATV is hard/soft and always varying its rattle space with body and suspension, longitudinal acceleration in forward motion and lateral acceleration when cornering. This property results reduced in steering stability, controlling and handling performance of the ATV by drivers. So we are giving a cost effective design of an All-Terrain Vehicle Frame and suspension system. Since the chassis is the integral part of an automotive, it should be strong and light weight. Thus, the chassis design becomes very important. Typical capabilities on basis of which these vehicles are judged are braking test, bumping, hill climbing, pulling, acceleration and maneuverability on land as well as shallow waters. The aim is to design a frame with ultimate strength to show that the design is safe, rugged and easy to maneuver. Design is done and carried out the linear static and dynamic failures of frame and suspension system.

All Terrain Vehicle for Defence

All Terrain Vehicle for Defence

The research paper deals with the designing and modeling of stair climbing robot based on the well-known rocker bogie mechanism. The concept of our research work is to create a rocker bogie drive system based on those of NASA. NASA Developed the rocker-bogie suspension system for their rovers and was implemented in the Mars Pathfinder's and Sojourner rover. The rocker-bogie suspension system passively keeps all six wheels on the robot in contact with the ground even on uneven surfaces. This creates for great traction and maneuverability (Harrington & Voorhees). The rocker-bogie suspension mechanism which was currently NASA’s approved design for wheeled mobile robots, mainly because it had study or resilient capabilities to deal with obstacles and because it uniformly distributes the payload over its 6 wheels at all times. It also can be used for other purposes to operate in rough roads and to climb the steps. It was having lots of advantages but one of the major disadvantages is the rotation of the mechanism when and where is required. The rotation can be possible by providing individual motors to individual wheels which causes arise in cost and complicacy in design. Here an attempt was made to modify the existing design by incorporating a gear type steering mechanism which will be operated by a single motor which simplifies the design as well as the total cost and operating cost of the mechanism.

A Review on Design & Analysis of All Terrain Vehicle Chassis

A Review on Design & Analysis of All Terrain Vehicle Chassis

As we have seen in most of the papers the design and manufacturing of different types of chassis has been discussed the main focus is given on the strength of the material which will be used for the design. The designing software used has been CATIA, Pro-E while the analysis is done on the ANSYS workbench. In the paper published by (Wang Guoqing) the analysis of all types has been performed mainly the stress analysis of the chassis. An improved scheme is put forward by analyzing the dangerous part of the chassis. The goal of all the designers has been to build a low cost ATV but not by compromising with its strength and other parameters. Most of the paper have been about the various analysis that have been carried out to create a chassis that is optimal on all the required parameters. (Denish S. Mevawala) This paper has mainly focused on the roll cage buildup. The aesthetics of the vehicle have been taken care of while designing. We have seen that the papers reveal a study of frontal impact, side impact, rear impact. The experiments conducted are very well planned according to the design considerations and parameters and made ensured that none of the components fail the test or break in the process of experimentation. (C.I.Chatzikomis) have compared the performance of a vehicle without any control system, a vehicle with ESC, a vehicle with 4WS and a vehicle with both systems. The objective has been to design the vehicle using the SAE rule book for various papers throughout the survey. The causes of fatigue failure in the ATV have been verified over and over and an optimal solution has been derived. A high performance ATV is all that is desired at the end of all the process. A prototype has generally been mode first in an attempt to check the vehicle for all the elements that have to be checked. (Hirak Patel) In his paper emphasizes on the weight reduction of the vehicle by carrying out a sensitivity analysis. The work has been focused towards the optimization of chassis with constraints of maximum shear stress and deflection of chassis. Thus, most of the paper have been about the various analysis that have been carried out to create a chassis that is optimal on all the required parameters.

Design and Development of All Terrain Vehicle : Volume 1

Design and Development of All Terrain Vehicle : Volume 1

The vehicle chassis includes the suspension and steering systems, frames ,tires, brakes, axles, and wheels [1] .ATV (All-Terrain Vehicle) is designed to operate in difficult and circuitous terrains. ATV consists of three main parts. These are chassis, drive train and suspension. In this study we deal with developing a unit of ATV called chassis/frame. The chassis is considered to be one of important parts of an automobile. Various important parts like the engine and the drive train, the axle assemblies, the suspension system, the brakes, the steering system, etc., are bolted on chassis. It provides the strength, rigidity required to support the different components. By designing the chassis with optimized parameter the level of noise and vibrations from different components is greatly reduced. To achieve this, Chassis should be rigid, so it can withstand different stresses and shocks (bending and torsional moments). So, strength and stiffness are two important factors considered while designing. Before manufacturing; Finite Element Analysis (FEA) is done to ensure designed chassis can withstand the loads and stresses acing on it.

Design and Failure Analysis of Two Stage Reduction Gearbox for an All Terrain Vehicle

Design and Failure Analysis of Two Stage Reduction Gearbox for an All Terrain Vehicle

The Old gear system had very little probability to cross 1500 Hours mark as shown in Fig.4 and Fig.5, all the dynamic components like Gears and Bearings were failed even before the designated life or the required life. So, compromising FoS (Factor of Safety) over size and compactness caused the failure which was a setback and another factor could be Gear Hunting [3] because for first pair pinion has 18teeth and gear has 56 teeth, so by calculating GCD (Greatest Common divisor) we can say that 2 nd tooth would have come under contact after every rotation and on that particular tooth stresses have been marginally higher. The second pair also had the same problem having 18 teeth on pinon 70 teeth on the gear, so every time 2 nd tooth would have been under contact after rotation. We will eliminate this problem in our new proposed design and another failure which were caused by bending and wear will also be eradicated from current operational design. So, to overcome these failures we have proposed a robust, Light Weight, compact, performance assured gearbox design with 10,000+ hours of service life reliability.

Design and Fabrication of Brake Pedal for All Terrain Vehicle

Design and Fabrication of Brake Pedal for All Terrain Vehicle

Abstract— The Brake pedal is again a very crucial component of an ATV as it would control the overall braking of the vehicle. Proper braking is very crucial in rough terrains with all four wheels locking so that the stopping distance is minimum. Hence a brake pedal needs to be designed in such a way it provides the necessary leverage and creates enough pressure for the brake fluid to reach all four wheels. A brake is a mechanical component that constrains the motion by absorbing the energy from the motion of the vehicle. When the brake pedal of the hydraulic braking system is pushed against the master cylinder, a piston pushes the brake pad against the brake disc which reduces the speed of the vehicle or stops the vehicle completely. Hence the brake pedal should be able to push the piston in the master cylinder completely with a full-length stroke and thereby provide equal pressure to all wheels.

Modelling and Optimizing of Vehicle Suspension

Modelling and Optimizing of Vehicle Suspension

A program for calculation and optimization of vehicle suspension consisting of rigid bodies, spring and damper elements was developed. First, mass, stiffness and damping matrices are constructed; then eigenfrequencies, mode shapes and damping of the whole system are calculated. Afterwards, all the necessary transfer functions for the generation of various spectra are computed. Vehicle ride comfort and dynamic tyre forces are also calculated. Initial models of vehicles can be verified and improved on the basis of comparison with measured acceleration autospectra. Optimization with respect to vehicle ride comfort and dynamic tyre forces can also be carried out. We measured road profiles of our roads, and later used these road profiles as input to our vehicle models. Results are shown on a model of the bus B3 090 T, with five degrees of freedom.

Design and Development of A Transmission System for an All Terrain Vehicle

and dynamic analysis of transmission system. The main principle of the transmission system is to supply required torque and power generated by the engine to the wheels as per driver’s requirement. The aim of this work is to economically simplify the design of transmission system in order to increase its performance and safety standards. This work comprises of material selection, gear box design, Finite Element Analysis (FEA) and simulation to test against failure. Since the All- Terrain Vehicle (ATV), is subjected to uneven and irregular road condition, constant and continuous power transmission should be considered in its design. For this, a combination of Continuously Variable Transmission (CVT) and designed gearbox is used to obtain the required reduction ratio. Design of transmission system is based on tractive effort, vehicle resistances, grade ability, and maximum vehicle speed. Considering all the above factors required reduction ratio is calculated. Finite Element Analysis (FEA) is considered for design validation.

Vibration Analysis of an All-Terrain Vehicle

Vibration Analysis of an All-Terrain Vehicle

IJEDR1601043 International Journal of Engineering Development and Research (www.ijedr.org) 252 Idle and low speed comfort can also be influenced due to changes of the engine excitation and the transfer mechanisms. The main transfer paths for the vibrations are the engine mounts, wheel suspensions and components mounted on to the body. The excitation becomes more critical when the main firing orders coincide with the Eigen frequencies of different components. The rigid body modes of the power train normally occur at very low frequencies. Care need to be taken while designing the mounting system so that the highest mode of the power train is at least √2 times lower than the first firing frequency of the engine. The presence of power train modes in the operating frequencies leads to higher transmissibility during low speed operation. When an engine is fastened directly to its support frame, it has a direct path for the transmission of vibration and noise. When the engine is attached to its support by means of properly selected resilient isolators, the path of vibration and noise disturbances is broken.
