The temperature field of damping buffers for viscoelastic suspensions mounted on crawler vehicles was analyzed under typical working conditions. The temperature correlation of the material was ignored to decouple the structure-thermal coupling field. The analytical results of structure were used as the basic conditions for thermal analysis. Because of nonlinear and large deformation under load, the temperature field was calculated by finite element method (FEM). The positions of local hot spots and temperatures under typical loads were obtained by computation. The curves of temperature against factors and its fitting equation on engineering applications were also determined. The results provide reasonable parameters for damping buffers structure optimizing.
