基于制动器钳体结构特征，建立了制动器钳体部件振动瞬态分析模型。模型有限元分析表明了各部件间模态振动频率，揭示了制动过程发生制动尖叫的主要原因是制动钳体零件间某阶频率十分接近；基于制动钳体和制动盘的谐反应有限元分析，分析表明，改变制动器钳体设计参数可在一定程度上改善制动器稳定性，特别是当制动盘厚度参数改变时，对制动器的振动稳定性和噪声的影响很明显。

A new vibration transient analysis model of the brake components are established based on the structural feature of calip. The finite element analysis(FEA) of vibration frequency among parts shown that the main mechanism resulting from squealing frequency occurs at the case of the natural frequency between the two parts being near. Based on the research of harmonic response FEA between brake calip and brake disc, it is evident that braking stability can be improved by changing the construction parameter of brake components. The analysis also shows that within certain range, to change the design parameter of the calip body can improve the stability of braking system. Especially, the sta-bility and breaking noise of the brake can effectively improved by increasing the thickness size of brake disc.
