Abstract

The title of this project is ‘Modelling of Front Suspension Module Using Flexible MBD Motion View’. Most times, the tire wear takes place due to the damaged shock absorber in the suspension strut. The side load acting on the spring is the main factor which causes the shock absorber to wear. This project converges into the problem and performs a new spring geometry with optimized spring force line to reduce the side load using analytical approach. In attempt to find and prove the optimized spring force line, two different spring geometries are compared analytically in strut level and verify the original spring force line in suspension level. The analytical comparison between the two spring designs involves experimental validation and evaluation in term of better spring force line with lesser deviation using HyperMesh. For the suspension level, the original spring model is simulated in a real ride condition and the spring force line is evaluated in the suspension system. The reduction of side load becomes the current target of the vehicle manufacturers and users where the tire thread sustained in a good condition after a long travel. A compromising shock absorber will keep excellent force absorption to preserve the comfort of the vehicle users. As a result of this analytical evaluation, the morphed spring design performs a side load reduction with the better spring force line.
