摘要

基于有限元理论和试验模态方法,对盘式制动器进行模态分析。通过CATIA软件建立制动盘的三维几何模型,之后导入到有限元软件ABAQUS中进行模态分析,得到制动盘的固有频率和模态振型。利用DASP和RTE两种设备对制动盘进行模态试验,得到制动盘的固有频率,并与有限元仿真的结果做对比。结果表明,利用3种方法测得的固有频率相差很小,误差在允许范围内,试验结果和仿真结果可以接受。最后,利用DASP和RTE两种设备测量制动盘的阻尼并做对比,所得的研究成果为进一步提高盘式制动器制动性能提供了可靠试验依据。
        Based on finite element theory and experimental modal method, modal analysis of disc brakes is carried out. The3 D geometric model of the brake disc is established by CATIA software. Then, import the model into the finite element software ABAQUS for the modal analysis to obtain the natural frequency and mode shape of the brake disc. At the same time, the modal test of the brake disc is carried out by using two kinds of equipment, DASP and RTE. The natural frequency of the brake disc is obtained and compared with the result of the finite element simulation. The results show that the difference between the natural frequencies measured by the three methods is very small, the error is within the allowable range, and the experimental results and the simulation results can be accepted. After that, the damping of the brake disc is measured by using two kinds of DASP and RTE equipment, and the results obtained provide a reliable experimental basis for further improving the brake performance of disc brake.
