摘　　要：盘式制动器是一种常用的制动装置,多用于汽车和其他运输设备。在工作过程中盘式制动器发生的各种振动对其工作性能有较大的影响,为了准确把握其振动特性,采用ANSYS软件建立盘式制动器零部件三维有限元模型,并进行约束模态分析,研究得到了关键零部件(摩擦盘和卡钳)的前六阶固有频率和振型,结果表明摩擦盘的第三阶固有频率和卡钳的第二阶固有频率较接近,可能引起系统的共振;研究结果为盘式制动器的优化设计提供了一定的理论参考。Disc brake is a common brake apparatus,which is used in car and other transporting equipment.The vibration has great influence on the performance of the disc brake in the working process.In order to accurately grasp its vibration characteristics,a three-dimensional finite element model of brake parts were established using ANSYS software and a constraint modal analysis was made.The first six order natural frequency and vibration model of disk and caliper were obtained.The results showed that the third order natural frequency of the friction disk and the second order natural frequency of the caliper is very close,which may cause resonance of the system.The research results provide certain theoretical reference for the optimization design of the disc brake.
