摘　　要：通过以东风德纳TD485后单驱动桥鼓式制动器为研究对象,对鼓式制动器接触的受力分析,忽略制动器零部件上加工的一些细节,建立其主要的受力部件(制动鼓、制动蹄、摩擦片)的力学模型。基于三维有限元软件UG建立鼓式制动器三维的有限元模型,利用大型有限元分析软件ANSYS workbench建立该制动器摩擦接触的关系,并对制动鼓进行摩擦接触的非线性分析,研究制动器在小角位移下制动鼓的应力分布和变形,为制动器的改进设计提供可靠依据。The thesis takes Dongfeng Dana TD 485 after single screw drum brakes as the research object to carry out stress analysis of drum brakes. The mechanical models of the main stress components（brake drum, brake shoe and friction plate） are established ignoring some details of brake parts processing. The 2D finite element model of rear drum brake is established based on the 3D finite element software UG, and the finite element analysis software ANSYS workbench is used to establish the friction contact relationship of this brake,and for nonlinear analysis of frictional contact of the brake drum. The stress distribution and deformation of the brake drum under small angular displacement are studied. It provides a reliable basis for the improved design of the brake.
