| 摘 要： | 试验研究制动器结构参数对制动噪声的影响，建立鼓式制动器高频噪声问题的结构闭环耦合模型，运用Ｈａｍｉｌｔｏｎ变分原理推导该问题的结构闭环耦合动力学方程。并针对某车通过改变制动底板的结构参数，利用本模型进行计算分析。”理论分析与试验结果在一定程度上定量一致。本理论模型是针对双领蹄型鼓式制动器建立的，但可在改变局部结构和边界条件的情况下适应于任何型式的鼓式制动器。

| Abstract: | The structurally closed loop coupling model of drum brake squeal is established on the basis of experimental study.The relevant equations of structural dynamics have been derived by applying Hamilton Principle,moreover;the model for numerical computation is formed.And the influence of structural parameters of structure of brake backplate,upon the drum brake squeal is studied in detail through computational analysis.The results of the theoretical study are consistent with those of experimental study quite well.Both experimental and theoretical studies have proved that the brake squeal of the drum brake system studied in this paper can be suppressed through stiffening the brake backplate. |
