摘要
随着汽车工业的发展,盘式制动器的制动稳定性及安全性受到广泛的关注。在盘式制动器的制动过程中,制动盘表面加工形式以及制动条件对制动盘的振动,噪声都会有直接的影响。首先对制动盘表面进行仿生设计。利用鸟类翅膀在飞行过程中具有阻力小的特点,使用MOPA激光器在制动盘表面加工出4种不同数量及深度的M型沟槽。使用洛氏硬度计制动盘盘面进行硬度测试,分析M型沟槽对其硬度的影响。在LINK3900台架实验设备上进行NVH台架实验,对比分析不同工况下M型沟槽对制动噪声和制动卡钳振动的影响,确定较好的设计方案。
With the development of the automobile industry, the brake stability and safety of disc brakes have received extensive attention. In the braking process of the disc brake, the surface processing form and the braking condition of the brake disc have a direct influence on the vibration and noise of the brake disc. In this study, the surface of the brake disc is firstly obtained through the bionic design. Four types of M-shaped grooves with different numbers and depths are processed by using the MOPA laser and the characteristics of low resistance of the bird wings during flight. The Rockwell hardness tester is used to test the hardness of the disk surface and the effect of the M-type groove on its hardness is analyzed. NVH bench tests is performed on the LINK3900 stand experimental equipment and the effects of M-type grooves on the braking noise and brake caliper vibration under different operating conditions are compared and analyzed to determine a better design solution.
