Sweep Sin Simulation for Exhaust System

Truck chassis forms the structural backbone of a heavy commercial vehicle. When the truck travels along the road, the chassis is subjected to vibration induced by road roughness and excitation by vibrating components mounted on it. The vibration of the chassis will also cause high stress concentrations at certain locations, fatigue of the structure, loosening of mechanical joints and creation of noise and vehicle discomfort. To solve these problems, study on the truck chassis dynamic characteristics is thus essential. This thesis concentrates on analysis of vehicle using virtual proto typing approach which includes simulation of load cases for tractor-trailer combination. This helps in to determine the loads acting on various components of tractor chassis, which are used as inputs to finite element model for stress analysis.
