Design And Analysis Of The Suspension System For Single Seated Educational Racing Vehicle

Generally, the suspension systems are categorized into two groups, dependent and independent system. A suspension connected to a rigid axle between the left and the right of the wheels is called a dependent suspension since the vertical movement of one wheel is delivered to the opposite wheel in these cases. The major disadvantage of this rigid steer able axle is their susceptibility to tramp-shimmy steering vibrations [6]. The independent suspension system allows the left and right wheel to move without affecting the other’s motion. Nearly all the passenger cars and light trucks use an independent front suspension because of the advantages in providing room for the engine and also for the better resistance to steering induced vibrations. There are many forms and designs of independent suspensions. However, double wishbone and MacPherson strut suspensions are perhaps the simplest and most commonly used designs.

Design analysis of helical spring of suspension system

Design analysis of helical spring of suspension system

Abstract – Helical spring has been widely used in the suspension system of the machines. This conventionally used spring was purely manufactured with the help of steel, which as a result increased the weight of the entire working machine, which was the hindrance in increasing its efficiency. Hence our project demonstrates the feasibility of adopting composite material for design of helical coil suspension system. In this project the design analysis of combination of steel and composite material will be performed. This will result into greater stiffness with reduced weight of the spring which will be the prime advantage of this project.

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

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

Although the MacPherson strut has its advantages, the Trailing Arm system is one of the most preferred rear suspension systems due to its functional design and sturdiness. It undergoes high bending and torsional stresses. Its advantage lies in the fact that there are no camber or toe-in changes, along with a constant track width. [4] The semi- trailing arm has also been considered for the rear suspension system. They have provisions for the adjustment of toe and camber angle for the rear wheels [5], and can be used to induce oversteer. A variation on this, in the form of a trailing arm with camber links has also been designed and analysis of the lateral, vertical and longitudinal forces acting on the components have shown this system to be a viable option. A degree of adjustment of the camber has been shown to be possible. [6] Some vehicles have also been run with wishbones at the rear. This gives good ride quality and toeing of the wheels has been eliminated; this has been confirmed by kinematic analysis. [7] An alternate approach to suspension kinematics is through control systems; second order equations have been used to present the suspension in control system form. The motion can then be observed by applying ‘disturbances’ to the equation in passive or active systems. [8]

Design and analysis of a nonlinear controller for vehicle active suspension system using sliding mode control

Design and analysis of a nonlinear controller for vehicle active suspension system using sliding mode control

One of the roots of vehicle vibrations and shakes is the road roughness. Shocks due to bumps on the road are transferred to the vehicle body through the wheels and not only make discomfort for passengers but also reduce the quality of driving. In this paper, a vehicle suspension system will be designed. Then its performance will be shown through analysis and simulation. The main idea is based on the combination of a nonlinear energy sink and a skyhook. The performance of the proposed suspension system will be evaluated by comparing car body vertical accelerations and suspension deflections with a passive suspension system. The sliding mode control as a robust nonlinear control method has been used to make the system robust to changes and uncertainties in car model. The Lyapunov based stability analysis shows that the tracking error of proposed system will asymptotically approach zero.

Design Analysis and Testing of an In Wheel Suspension System

Design Analysis and Testing of an In Wheel Suspension System

MATLAB’s optimization functions such as fminmax can be used to optimize the shape of the Castigliano spring to design a spring with a specific stiffness. Figure 3.5 shows a sample spring inside a wheel's rim. The graph on the right shows the spring's equivalent stress. A simple proof of concept for a non-rotating in-wheel suspension system is designed using the code (Figure 3.6). The design consists of four pivot joint springs and two cantilever springs. Four pivot joint springs are used instead of two to achieve a symmetric design and also to increase the capability to handle out of plane forces. The cantilever springs are added to the design to boost the horizontal stiffness of the design. Although, the Castigliano method can be used to design and optimize springs for the IWS, but analytical integration and solutions takes a long time in comparison to FEA methods. Moreover, the model is constrained to analytically shaped springs with small deformation; however, one of the objectives of a suspension spring is to provide as much as wheel travel as possible. To overcome these restrictions, a more advanced spring optimization tool developed in the next section.

Design and Analysis of Leaf Spring Bracket in Air Suspension Vehicle Using FEA

Design and Analysis of Leaf Spring Bracket in Air Suspension Vehicle Using FEA

The schematic diagram of the Air suspension system is shown in the fig 1. It consist of four no of parts, these components are mounted in the chase except leaf spring. The component of bellow, shock absorber and bracket is mounted on the chases of the vehicle. The other end of the bellow and bracket is connected by using double stand leaf spring. The other end of shock absorber is fixed along with axel. This is the fixing arrangement of air suspension system. Whenever force exerted on the system the shock absorber and bellow absorb the force by means of leaf spring. One end of leaf spring is mounted below the bellow and other end is fixed with bracket. So whenever force exerted on the system it is also absorb by the bracket. The same process repeated when the vehicle is moving in the road due to road irregularity. Due to which bracket under goes fatigue load. So it leads to bend in the bracket and crack formation.

Dynamic Analysis of the Front and Rear Suspension System of an All Terrain Vehicle

Dynamic Analysis of the Front and Rear Suspension System of an All Terrain Vehicle

Suspension system is an important part of vehicle which provides comfort, control and safety to the passengers. It allows vehicle to travel over rough surfaces with minimum up-and-down body movement. Suspension is defined as isolation of two masses hence while designing suspension, a balanced design should be provided in order to carry out functions like road holding, load carrying and passenger comfort. It consists of arms, damper, spring, joints, tire, knuckle and hub. it is necessary to design a suspension system that can handle the roughest of terrain and endure extreme force conditions without affecting the vehicle’s stability and at the same time also provide a smooth ride to the driver.so it has been decided to go for the double wishbone in front and h-arm in rear with a dual rate spring system, so that it can sustain the design load and give excellent comfort and control over the off-road, providing safety to the driver.

Analysis on passive vehicle suspension system

Analysis on passive vehicle suspension system

Vehicle suspension system plays an important role in automobile industry in order to guarantee good ride quality of vehicle. Basically, traditional suspension system which is passive suspension system consists of springs, shock absorbers and linkages that connect a vehicle body to its wheels . However, passive suspension system is an open loop system which does not contain any controllers to control the performance of the vehicle suspension system when passing through bumpy on the road. In this report, construction of an experiment setup to represent passive vehicle suspension system for quarter car model is considered. Experimental setup for passive suspension system is important because proper modeling of vehicle suspension system could lead to good controller design and hence improve the performance of the vehicle suspension system. This report primarily focuses on the two- degree-of freedom quarter-car model to represent passive suspension system. Semi-active and active suspension system will not be covered in this project A number of experiments have been carried out using the experiment setup in order to identify the characteristic of this experimental setup. Experiments with different vehicle body mass, different period for one pulse and different pulse width of input pressure of the road excitation have been conducted. The experiments results are evaluated based on the vehicle body displacement and tire displacement of the experimental setup. However, experiments give different results when three parameters are varied. Experiment results show that the pulse width of the input pressure is directly affected the characteristic of this passive suspension system experimental setup. Lastly, simple simulation has been done in order to compare the simulation and experiments results. The amplitude and shape of the simulation and experimental results are evaluated in this report.

System Approach to Vehicle Suspension System Control in CAE Environment

System Approach to Vehicle Suspension System Control in CAE Environment

1 DESIGN DEVELOPMENT PROCESS The design procedure, which is to be carried out in the case of mechatronic systems, is very demanding - it is necessary that system engineering, within the field of mechanics, electronics and computer science, forms a completely integrated system. Hence, intelligent testing technologies, supported by CAE (Computer Aided Engineering), which provide numerical simulation models, are to be employed during component development and their qualification. An emphasis should be placed upon the interaction between computer aided system simulation and experimental testing techniques through intelligent information processing. CAE is a technology that enables computer analysis of the design, created within CAD (Computer Aided Design) technology. By the application of CAE technology it is now possible to have a much better linking of design, testing and design improvement, which are the development phases that have, so far, been almost separate. Fig. 1 shows a diagram of design development process [4]. After theoretical modelling and experimental system identification, the future design steps are control system analysis and model based controller design. The demands for efficient optimisation and testing include:
