本文利用有限元计算模态和试验模态两种方法对制动底板进行结构模态分析,获得制动底板振动的前几阶主频率,为进一步分析制动噪声打下基础。
In this paper, finite element method and test modal two methods are used to analyze the structural mode of the brake floor to obtain the main frequencies of the first few stages of brake floor vibration, which lays the foundation for further analysis of the brake noise.
