Abstract
Finite element analysis of automobile drum brake assembly was made in this article. First brake drum assembly 3D model including brake drum, brake shoe, brake block, and friction plate was established; then finite element analysis of drum brake assembly was made, considering the friction between assemblies as well as the relative sliding between brake shoe and brake block, brake block and friction plate. The simulation of automobile’s braking was relatively authentic, drum brake’s stress and displacement deformation at work was analyzed. The results showed that with fixed brake drum, left and right brake shoes’ load was completely symmetric, stress and displacement distribution was also completely symmetric; in the process of braking, one side brake shoe’s stress and displacement were obviously bigger than the other side, max stress occurred on one side brake shoe’s internal end face.
