为有效控制制动尖叫,本文中针对制动块背板弹性模量、衬片弹性模量、衬片开槽方式和衬片斜角角度进行了设计。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的基础上,提出了一种基于尖叫试验结果的加权尖叫倾向性指标作为稳健性设计目标,以摩擦因数的波动为干扰因素,采用田口方法进行了面向尖叫的制动块稳健性设计。结果表明,制动块衬片的弹性模量对制动尖叫的影响最大;所采用的方法能获得有效而稳健的制动块设计参数组合。
For effectively controlling brake squeal, a robust design for brake squeal is conducted in terms of the elastic modulus of back plate, the elastic modulus, slot pattern and edge chamfer of lining of brake pad. A finite element complex modal model for disc brake is established and validated by bench test. Based on this, a robust de- sign of brake pad for squeal is performed by using Taguchi method, with a weighted indicator for squeal tendency based on squeal test results as the objective of robust design and the fluctuation of friction coefficient as disturbance factor. The results show that the elastic modulus of pad lining has the most influence on brake squeal, and the meth- od adopted can get the parameter combination for the effective and robust design of brake pad.
