中文摘要：

在建立盘式制动器复模态有限元模型并通过台架试验验证模型正确性的基础上,提出了一种以加权尖叫倾向性作为稳健性设计指标的方法,以摩擦系数的波动为干扰因素,采用田口方法进行了制动盘弹性模量、帽部高度、帽部直径和通风散热筋数量的尖叫稳健性设计。分析表明,制动盘的弹性模量对制动尖叫稳健性的影响最大且采用所建立的方法能够获得可有效控制试验制动尖叫的稳健的制动盘设计参数组合。

英文摘要：

A finite element model of disc brake based on complex modal analysis was established and validated through bench test, and a new robustness index for brake squeal named weighed tendency of instability was highlighted taking into account the brake squeal test results. Taking friction coefficient as noise factor, robust design of brake rotor parameters which include the elastic modulus, hat height, height diameter and the number of ventilating fins against brake squeal was completed based on Taguchi method. The deign results show that elastic modulus of rotor has the foremost influence on brake squeal robustness, and the established method can achieve robust design parameters of brake rotor, which can effectively reduce brake squeals that occur in the bench test.
