Abstract

Taking a two-axle truck for research object, a mathematic model and FEA model of 10 degrees of freedom finished automobile are established to describe the vibration of the truck. Virtual excitation of road is constructed through the basic theory of virtual excitation method and its statistical properties of the actual response are obtained. FEM theory is used in discrete the truck vibration structure model and stiffness matrix and damping matrix of each element are assembled in accordance with the node degree of freedom. Taking forced displacement constraint handling methods, truck vibration differential equations are obtained. The research methods and results used in this paper will provide a useful reference for vibration and ride comfort design of trucks.
