Application of Rigid-Flexible Coupling in Stiffness Calculation of Double Wishbone Suspension

Abstract:

Based on multi-body Dynamics theory, the 1/4 multi-rigid model of double wishbone suspension of automobile in ADAMS/View is created, and use ANSYS software to analyze torsion beam flexibility. Furthermore, the rigid-flexibility model has been created and the rigid change of suspension line along with the tire dynamics change is simulated. The result shows that the rigid-flexible coupling model is more accuracy than the multi-rigid one and fits the practical situation even better. This paper proposes an efficient method for analyzing the rigid of double-wishbone suspension vertical line.
