摘要

针对汽车盘式制动器在制动过程中的噪声抑制问题，考虑制动不平衡量及制动器参数不确定性的影响，结合响应面法、有限元法与可靠性分析理论，提出了一种含混合参数模型的盘式制动器振动稳定性的可靠性分析方法。采用随机、不确定区间和模糊参数来描述制动系统的动态特性，建立含随机参数、不确定区间参数和模糊参数的盘式制动器系统不稳定阶次响应面代理模型，通过对系统振动稳定性的参数灵敏度分析获取其影响显著因子，在Design Expert软件中对制动时的振动稳定性进行可靠性分析，揭示了各因子2阶交互作用对其可靠度的影响规律。用该方法对某型汽车的钳盘式制动器进行验证，结果表明，含有混合参数的制动器系统在稳定性不理想的情况下，通过增加其支撑背板厚度或提高弹性模量，可以有效改善制动系统的稳定性。

Abstract

In view of the brake squeal suppression problem of automotive disc brakes during braking

the effects of brake imbalance and uncertainty in brake parameters

a stability and reliability analysis method of disc brake with the hybrid parameters was proposed by combining response surface methodology

finite element method

and reliability analysis theory. In this method . random

uncertain interval and fuzzy parameters were used to describe the dynamie characteristies of the brake system

and an unstable order response surface agent model of the disc brake system was established including random parameters

uncertain interval parameters and fuzzy parameters. Then

the remarkable affecting factors were obtained through sensitivity analysis of stability and reliability on brake system. Therefore

the influence laws of the second-order interaction of each factor were analyzed deeply based on stability and reliability analysis in Design Expert software. This method was used to verify the caliper disc brake of a certain type of automobile

and the results show that when the stability of the brake system with mixed parameters is not ideal

it can improve the stability of brake system effectively by increasing the thickness and elastie modulus of back plate of brake system.
