The finite-element analysis of the brake stamping-welding shoes was conducted

based on software of ANSYS Workbench. Firstly

the sinusoidal distribution rule of positive pressure and friction force along the cambered surface of the brake shoe was analyzed. Then

the discrete loading method of positive pressure and friction force and the boundary conditions was established in a 3-D model. Finally

the size of deformation

stress

strain and the distribution of brake shoes were calculated. The results indicate that deformation

stress distribution of the brake shoes are even

the maximum deformation and the maximum stress occur in two webs with narrow spacing

but they are not beyond the scope of design requirements.
