Abstract
The thrust rod for a heavy-duty commercial vehicle suspension system as the research object, the application of finite element method analysis of the static radial characteristics of rubber spherical joint. Introduces the basic theory of constitutive relationship of rubber materials, thrust rod established the finite element model, calculation and analysis of the influence degree of spherical joint structure parameters on the static characteristics of rubber spherical joint. The results show that, the circumferential diameter rubber increased properly and bush using plastic layer can improve the rubber bushing stiffness, and reduce the maximum stress.
