对一盘式制动器高频尖叫及抑制的分析

ANALYSIS OF A DISC BRAKE HIGH FREQUENCY SQUEAL AND REDUCTION

  • 摘要: 针对某制动器存在的13kHz高频尖叫、在制动片上安装了消声片及对摩擦片形状进行加槽和倒角后仍得不到抑制的问题,通过对其建模和应用该课题组研究确立的系统分析方法,包括复特征值分析、子结构模态构成分析、子结构模态参数灵敏度分析以及能量馈入分析方法等,进行了系统分析,找出了影响该阶高频尖叫的关键子结构的关键模态,指出了修改方向,通过优化设计方法给出了修改部件,并得到了模拟验证。

     

    Abstract: A disc brake generates high frequency squeal at 13 KHz, and cannot be reduced by introducing noise insulators and cutting chamfers at pad ends. A complete close-loop coupling modal synthesis model is built. A series of analytic methods, including complex eigenvalue analysis, substructure modal composition analysis, substructure modal parameter sensitivity analysis and feed-in energy analysis, etc. is utilized to perform a systematic analysis. Substructure modal parameters which are critical to the squeal problem are found and structure modification directions are identified. The modification is performed through optimization design. The results are verified through simulation.
