基于ABAQUS的湿式多盘制动器制动噪声分析

Analysis on Wet Multi-disc Brake Noise Based on ABAQUS

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。

Take the wet multi-disc brake of underground engineering truck as research object,combined with the complex modal analysis theory and FEM,and establish the FEM model of the wet multi-disc brake based on ABAQUS.Through complex modal analyzing on the wet multi-disc brake,obtain the main factors of brake noise during braking and provide improved measures to decrease the brake noise combined with analysis results.It provides a good theoretical basis in researching the brake noise and has practical engineering significance.
