摘要：利用有限元分析方法,针对某型轿车盘式制动器进行刹车产生噪声的数值仿真。通过改变一系列参数,例如摩擦系数,刹车前速度以及制动盘的几何形状等,考察其对刹车噪声的影响。然后通过模拟结果与实验结果比较,证实了文章所提出的仿真计算模型的有效性。最后提出了制动器设计的改进建议。
With finite element analysis, brake noise in the disc brake system was built and simulated. A disc brake with squeal tendency was studied by changing parameters of disc brake system such as coefficient of friction, wheel vector and geometric shape of disc brake. Results of finite element analysis quite agreed with experimental investigation of disc brake squeal, so that the model was accurate enough in engineering application. Some suggestions of improvement design were also proposed.
