以井下工程车辆的湿式多盘制动器为研究对象,结合复模态分析理论和有限元法,建立了基于ABAQUS的湿式多盘制动器有限元分析模型。通过对湿式多盘制动器进行复模态分析,得到了制动过程中产生制动噪声的主要影响因素,并结合分析结果给出了减小制动噪声的改进措施。为研究制动噪声分析提供了很好的理论依据,具有实际的工程意义。 Taking the wet multi-disc brake of underground engineering vehicle as the research object, the finite element model of wet multi-disc brake based on ABAQUS is established by combining the theory of complex mode analysis and finite element method. The main influencing factors of braking noise during braking are obtained through the complex modal analysis of wet multi-disc brakes. Combining with the analysis results, some measures to reduce the braking noise are given. It provides a good theoretical basis for studying the analysis of brake noise and has practical engineering significance.
