本研究利用表面接触分析模式，对碟形煞车尖叫振动的稳定性进行分析。在实验结果中，声压级和尖叫的频率取决于推力压力。我们认为，造成这种现象的原因是轴瓦的刚度取决于接触区的推力。因此，我们建议使用表面接触分析模型，它结合了一个磁盘与垫卡钳分布弹簧。基于实际的尖叫振动，盘具有平移运动，而垫-卡钳具有平移和旋转运动。该模型的分析结果与实验结果吻合较好。
This study presents the stability analysis of squeal vibration on disk brakes by a surface contact analysis model. In experimental results, the sound pressure level and the frequency of squeal depend on thrust pressure. We think the cause of this phenomenon is that the stiffness of the pad depends on thrust pressure in contact region. Therefore, we propose to use the surface contact analysis model which combines a disk with a pad-caliper by distributed springs. Based on the actual squeal vibration, the disk has translational motion while the pad-caliper has both translational and rotational motions. The analytical results by this model are in good agreement with the experimental results.
