This paper analyzed the temperature field of one large mining machinery disc brake during normal braking conditions in ANSYS. Basing on the sequential coupling methods, analyzed the brake disc's thermal stress distribution and changes. According to the analysis results, estimated its thermal fatigue life.

According to the crane dynamics theory, the dynamical model of a bridge crane's three main mechanisms is established and the dynamical load is determined under different work conditions in the paper. The three-dimensional solid model of the bridge crane is built by Pro/E, and then which is imported in ADAMS through the interface module of Mech/Pro. The virtual prototype model of the bridge crane is formed in ADAMS when relevant constraints and loads are applied. Based on the model, the bridge crane’s kinematics and dynamics performances are simulated and analyzed, and which shows that the simulation results can provide valuable guidances for design of the bridge crane.
