Abstract

The use of optical fibre Bragg gratings (FBGs) to monitor the Interface Pressure Distribution (IPD) on an automotive disc brake pad under a variety of loading conditions is studied. The results demonstrate successful strain transfer from the brake pads to the attached FBG sensors under static loading, with a linear response to increasing pressure, and with the measured IPD showing good agreement with that recorded using pressure sensitive paper. Results are also presented demonstrating that changes in the IPD as a result of torque acting on the brake pads can be monitored by the FBG sensors.
用于分析盘式制动器/衬垫界面压力分布的光纤布拉格光栅传感器
研究了利用光纤布拉格光栅(fbg)监测汽车盘式刹车片在不同载荷条件下的界面压力分布。结果表明,在静态负载下,从刹车片到附加的FBG传感器的应变成功传递,随着压力的增加呈线性响应,并且测量的IPD与使用压敏纸记录的IPD显示出良好的一致性。结果还表明,由于扭矩作用在刹车片上,IPD的变化可以通过FBG传感器进行监测。
