摘　　要：结合复模态分析理论和有限元法,在ANSYS平台上,利用自定义的摩擦单元实现了制动盘和制动块间的摩擦耦合,并用约束方程实现了盘式制动器中其它部件间的连接,建立了盘式制动器的有限元模型。最后以某典型盘式制动器为例计算了18kHz以下的复模态,并分析了其与制动噪声的关系。The FEA complex modal analysis model of a disc brake is set up with the combination of complex modal analysis theory and FEM. In ANSYS software, the friction couple between disc and pads is realized with custom friction elements, and the joints among other parts of the brake are achieved with constraint equations. Finally, the complex modes of the typical disc brake under 18kHz are calculated, and the relationship between the complex modes and brake noise is analyzed.
