针对汽车盘式制动器的制动尖叫问题,提出了一种基于加权制动尖叫倾向系数作为制动尖叫性能评价指标的方法。在建立盘式制动器复模态有限元模型的基础上,通过噪声台架试验验证了模型的有效性;将中心复合试验设计、响应面(RSM)代理模型法和Pointer优化算法相结合,以加权制动尖叫倾向系数最小为优化目标,对制动盘的单侧盘面高度、散热筋高度、弹性模量和盘帽高度进行了结构优化设计。结果表明,提出的优化设计方法能够显著提高优化求解的效率,有效降低盘式制动器在全频段内的尖叫倾向性,抑制制动尖叫噪声的产生。
Aiming at the problem of brake squeal of automobile disc brake, a method based on weighted brake squeal tendency coefficient is proposed to evaluate the brake squeal performance. On the basis of establishing a complex mode finite element model of the disc brake, the validity of the model is verified by the noise bench test. By combining the central composite test design, Response Surface Method (RSM) surrogate model method and the Pointer optimization algorithm, and taking the minimum weighted brake squeal tendency coefficient as the optimization goal, the structural optimization design is carried out for the unilateral disc height, heat sink rib height, elastic modulus and disc cap height of the brake disc. The results show that the optimization design method proposed can significantly improve the efficiency of the optimization solution, effectively reduce the squeal tendency of the disc brake in the full frequency band, and suppress the generation of brake squeal noise.
