摘　　要：本文研究盘式制动系统模态特性,通过实验测试和有限元分析得到制动盘自由和耦合振动模态,验证对称结构振动的正弦和余弦模态假设,提供环形梁简化模型的分析依据,比较摩擦块与制动盘耦合振动和制动盘自由振动的异同.动态测试得到耦合系统的位移响应.Numerical simulation and experimental exploration to study the dynamic characteristics of the disc brake system,and the main content are shown in this paper.Partial results are verified by the experiment and finite element analysis.Disc’s modes with different pitch circles and pitch diameters are proposed.The orthogonal bending modes and torsional modes are proposed.Frequencies of the pad-on-disc coupled system are tested and responses are attained by dynamic experiments.
