Study of dynamic behaviour of truck chassis

Truck chassis is a major component in a vehicle system. It integrates the main component systems such as the suspension, engine, cab and trailer. Thus it often identified for refinement in order to develop vehicles with reduced cost and weight. Nowadays with the capabilities of advanced computer aid...
