【摘要】 基于实模态分析理论和有限元法,研究了某盘式制动器的制动噪声问题,分别建立了制动盘、制动块、制动钳钳体和制动钳支架的有限元模型,计算了它们固有频率在20 kHz以下的各阶实模态,并对与制动噪声有关的各阶模态进行了分析。更多还原

【Abstract】 The braking noise problem of a disc brake is studied based on real modal analysis theory and FEM.The finite element models of the disc,block,caliper body and caliper frame of the disc brake are established.Real modes under 20kHz are calculated,and the modes related to brake noise are analyzed.更多还原
