摘　　要：用有限元分析方法,对汽车鼓式制动器制动蹄的动态特性进行理论计算和研究。建立制动蹄和摩擦衬片的有限元模型,应用有限元分析软件ANSYS对模型进行分析计算,得出制动蹄和摩擦衬片的各阶频率及其振型,并对计算结果进行模态分析。在模态分析和模态振型的基础上,提出修改制动蹄的结构参数、材料参数以及在模型上添加质量块或加强筋的措施与方法,以错开各零部件的固有频率范围,降低振动噪声。Using finite element analysis method,the calculation and study of dynamic characteristics on the brake shoe of automobile drum type braker are performed.A software-ANSYS is used to create finite element model of brake shoe and friction liner,and analyze their dynamic behaviors.The inherent frequencies and the vibration modals are obtained,and the modals and the influence factors are analyzed interiorly.Based on this modal analysis,these measures and methods are proposed that modifying brake shoe＇s structure parameters and the material parameters and increasing the quality block or reinforcing rib on the model to stagger the brake shoe natural frequency scope and reduce the vibration noise.
