摘　　要：由于制动盘制动时产生的振动会造成制动噪声和闸片与制动盘之间的接触不均匀,因此研究制动盘的振动特性对于分析整个制动系统的工作性能具有重要的意义。以日本千叶县0系悬挂式单轨车辆为基础,建立制动盘以及制动闸片的实体模型,进行了自由模态和约束模态的有限元分析,得到了制动盘和制动闸片的前8阶固有频率,分析了两者的振动特性,为制动系统未来的优化和改进提供了理论依据。Vibration during disk brake process will generate brake noise and uneven contacting between brake pad and brake disk, so it is important for analysis the whole disk brake system＇s performance to research the vibration characteristics of the brake disk. Based on the Japan Chiba Prefecture type 0 suspended monorail vehicle, the solid model of brake disk and brake pad was established, and a fi nite element analysis of free modal and constrained modal was taken out, and the preceding eight natural frequencies was obtained. Based above, the vibration characteristic of both brake disk and brake pad was analyzed, which provided the theoretical basis of brake system＇s optimal design.
