Abstract :
In this paper a new method based on the techniques of virtual prototype and optimization algorithm to redesign the suspension system of tracked vehicle is proposed. Firstly the multi-body dynamic model of the vehicle before refitted is established and validated through the field test. Then the refitted virtual prototype model is established from the validated model. To be satisfied with the refitment requirement, the stiffness of torsion bars spring of the suspension system of this new model is optimized by the optimization design technique. To verify the feasibility of the optimization results, the virtue validation for the dynamic stress of torsion bars spring and ride comfort of the refitted vehicle model is taken. The optimization results that meet with the refitment requirement can be found. This provides a novel effective design scheme for the refitment of the vehicle.
