摘　　要：基于台架实验机的简化模型,通过ABAQUS仿真预测出尖叫频率。通过比较不同制动工况参数以及改变摩擦片的结构,发现速度越小,压力越大,摩擦系数越大,系统越不稳定,即尖叫声压级越大。TM-1制动台架实验机模拟汽车制动过程,对粉末冶金摩擦片进行多种工况下的制动实验,通过测试设备测得尖叫频率。与仿真结果对比,发现利用复特征值分析可以找出影响制动噪声的主要因素,但对噪声频率的预测有一定的偏差,需要建立更准确的有限元模型和统计模型。Based on the simplified FEA model of bench test machine,the squeal frequency is predicted in ABAQUS.As thebraking parameters and structure of the friction plate are changed,it is found that with the decrease of the rotational speed,theenlargement of brake pressure and the friction coefficient,the system is more unstable,and the sound level of the brake squeal ishigher.Through the TM-1bench test machine to simulate the automobile braking process,it is found that we can find the maineffect factors on braking squeal with complex eigenvalue analysis,however,there is a certain of deviation on the prediction offrequency,it is necessary to establish a more accurate finite element model and statistical model.
