摘要：
The structure and principle of a new type of electromechanical composite brake are introduced. The three-dimensional model of the composite brake is established. According to the working state of the braking system, the coupling field between heat and force of the electromechanical composite brake is analyzed. The finite element model of structure coupling between electromagnetism and force of the electromechanical composite brake is established. Through the finite element analysis on the electromagnetic field, the electromagnetic force distribution of excitation coils is obtained. The dynamic analysis of the composite brake is carried out, the distribution of equivalent stress and deformation is obtained. The analysis results show the temperature rise and deformation of electromechanical composite brake are less than the traditional friction brake, which can effectively reduce the thermal recession in the process of automobile braking. And the maximum deformation of excitation coils can meet the requirements of the materials. The stress change of brake disc is very little to the electromagnetic field, which can fully guarantee the braking performance of electromechanical composite brake in the process of emergency braking. Therefore, the multi-field coupling analysis to electromechanical composite brake can provide a theoretical reference for the improvement design of automobile brake.
