The thermal-structure coupling analysis of crane disc brake based on the bench test
The brake is an important safety device of the crane, and its temperature distribution affects the braking performance, while the bench test is an important method to test the brake’s quality. In the paper, the 3D transient thermal-structural coupling finite element model is constructed according to the actual size of brake, with the bench test data at different initial speed as input boundary conditions, the model is based on the heat conduction and thermal stress finite element analysis theory. By simulating the braking process, the regularities of temperature/stress field distribution at different initial speed are analyzed, which is coupled and varied with the braking time, the temperature and equivalent stress of the brake disc are increased with those of the initial speed. The simulated temperature of thermal-structural coupling finite element model is consistent with the measured
