Strength Analysis on Automobile Chassis B Ramana Naik & C Shashikanth

Abstract: The word automobile has been very much sought after since the very past. They are used in various modes of transport. The load that should be carried by it depends upon the type of vehicle into which it is classified, and this classification is done depending on the load it has to carry. The load carrying structure is the chassis. All the components of the automobile are mounted over it. So the chassis has to be so designed that it has to withstand the loads that are coming over it. This paper aims at analyzing an automobile chassis for a 10 tonne vehicle. The modeling is done using Pro-E, and analysis is done using Ansys. The overhangs of the chassis are calculated for the stresses and deflections analytically and are compared with the results obtained with the analysis software. Modal Analysis is also done to find the natural frequency of the chassis and seen that it is above than its excitation frequency.

Analysis and Optimization of Weld Distortion in Automobile Chassis

Analysis and Optimization of Weld Distortion in Automobile Chassis

The chassis provides the strength needed for supporting the different vehicular components also to support the payload and helps to keep the automobile rigid and stiff. The chassis is an important component of the overall safety system of any vehicle. Chassis structure also ensures low levels of noise, vibrations and harshness throughout the automobile. Chassis should be rigid enough to withstand the shock, twist, vibration and other stresses. To perform above stated operations efficiently chassis building should be strong enough; Welding Process plays an important role in chassis building Welding distortion, a result of the non-uniform expansion and contraction of weld metal and adjacent base metal during the heating and cooling cycle of the welding process, is a major concern during the fabrication of a welded structure. Welding distortion causes complex consequences. In this project the chassis assembly is to be analyzed for the various different weld sequences, using the transient thermal and transient structural analysis in ANSYS software.

restructured. The dynamic stress test of the whole truck was implemented to obtain the peak stress of the mainly forced area, which was compared with the simulated stress. It was found out that the error was allowable so that the accuracy of the finite element model was definitely ensured. The quasi- static stress analysis method was employed to acquire stress influence coefficient under unit load, which was associated with load histories of the frame to get the dangerous stress area. The fatigue life of the frame was calculated on the basis of Palmgren–Miner damage theory. It was turned out that the minimum life area of the frame is located at the frame joints of suspension, which matches the practice. More recently, Bhat et al. in 2014 [9], redesigned a modified chassis for tractor trolley.

Study on Impact of Chassis on the Performance of an Automobile with NEDC Simulation

Study on Impact of Chassis on the Performance of an Automobile with NEDC Simulation

the vehicle’s performance characteristics such as its acceleration performance orand improve its fuel economy. Hence, here the Performance-Size-Fuel economy Index (PSFI) which is the product of the vehicle’s power to weight ratio, the vehicle’s inside volume and fuel economy has been used to quantify the extent of trade-offs between the automobile’s performance, size and fuel economy (An &DeCicco, 2007). The difference in thePSFI values for each automobile can be directly attributed to factors like power loss due to road load which is the sum of power loss due to rolling resistance coefficient (RRC) and aerodynamic drag force (Gillespie, 1992) and inertia of automobile chassis. These factors influence the automobile’s acceleration and braking performance thereby impacting the performance and fuel economy of the automobile. In order to obtain these results, a car from each category namely Sports Utility Vehicle (SUV), Multi Utility Vehicle (MUV), Hatchback and Sedan were selected to have similar engine displacement of around 1200 cc. The New European Driving Cycle (NEDC) was implemented for simulating the driving cycle of all the selectedcars. TheNEDC has a road profile of straight roads, hence the load transfer during cornering and steering kickback diminution parameters are the limiting parameter of the simulation study (Rajeshkumar, Balasubramaniam, Bhavanakumar, Thirumalini, 2013).

Fabrication of Agriculture based Smart Cultivation System

Fabrication of Agriculture based Smart Cultivation System

In this smart agricultural cultivation system, we use the engine with a displacement of 125cc i.e., 125 cubic centimeters and the type of an engine is 4-stroke single cylinder engine .125cc is the volume swept by the piston of an engine when it goes from top dead center to bottom dead center. The piston reciprocates inside the cylinder of an engine .When the piston is at the lowest end of the cylinder it is said that the piston is in bottom dead center. Dead centers are the two ends of the engine cylinders and the volume between them is “cc” ( here 125cc ). Generally for the four wheeler vehicle the engine is placed on the front portion of the vehicle, in this vehicle we placed the engine on the back portion of the vehicle which is fixed by two bolts and nuts into the welded part on the chassis. The power of the engine is 6500 rpm when it runs on the agricultural field it may varies. This engine consists of kick start and self start switch also.

Automotive Chassis Topology Optimization: a Comparison Between Spider and Coup´e Designs

Automotive Chassis Topology Optimization: a Comparison Between Spider and Coup´e Designs

The cases 5 and 6 (Figs. 3(e) and 3(f) for the chassis layouts, and Figs. 3(g) and 3(h) for the roof layouts) are coup´e versions of the cases 3 and 4 respectively. In these cases, the beams are much thinner compared to their spider versions, as a consequence of the fact that a portion of the load is carried upwards through the roof of the vehicle. This also allows the final structure to be much simpler (a lower number of beams is found in the solutions), and the central tunnel to disappear completely. Despite the fact that in case 5 (Fig. 3(e)) local stiffness load cases are not included, spanwise structures appears both on the front and on the rear of the chassis. These structures converge towards the areas in which the roof is connected to the rest of the chassis and serve to transfer the loads between the chassis and the roof. The spanwise structures are still present and even reinforced in case 6 (Fig. 3(f)) due to the local stiffness loads. It is interesting to notice how the bumpers in both the copu´e versions are more distant from the ground level, are not parallel to each other but slightly converging, and their two support beams are less slanted and meet nearer to the car front. These things suggest that the lines of force in the event of front crash are going to remain higher on the level ground and be pushed towards the sides of the car in order to go through the roof structure.
