Lateral Dynamics Simulation of a Truck with Modified Rear Suspension

Due to the practice of lifting the rear suspension of heavy trucks, adopted by some end-users in Brazil, and in order to supply theoretical propositions to the manufacturers of suspension components for product improvement, this work describes stability and lateral dynamics tests simulations of a 4×2 rigid truck with 15000 kg of gross vehicle weight (GVW) and with changes in its originals leaf springs, predicting its dynamics responses in cornering and safety against rollover when unloaded and loaded at its GVWR limit.
