摘　　要：针对汽车盘式制动器制动过程中的振动问题,以模态分析理论为基础,通过三维软件UG建立盘式制动器主要零部件的模型,利用有限元软件Ansys-workbench对其进行了有限元模态分析,提取了其前6阶模态进行了详细分析,得到了制动器主要部件的固有频率和模态振型,避免了盘式制动器主要零部件之间可能出现的共振,为降低制动过程中出现的振动以及结构优化提供理论指导。The modals for main components of the brake disc are established by using three-dimensional software UG. Finite element modal analysis of automotive brake disc is carried out by using the finite element software Ansys-workbench based on modal analysis theory. Their front sixth order modals are extracted. The natural frequencies and mode shapes of the main components of the brake disc are obtained. This research can avoid resonance that may occurs between the main components of the brake disc and it can provide theoretical guidance to reduce vibration and optimize structure.
