| 摘 要： | 对某型轿车盘式制动器进行了台架试验,发现该制动器主要制动噪声频率在3kHz附近。采用有限元FEA分析手段对制动盘、制动钳壳体、制动钳支架和摩擦片进行了振动特性分析。结果表明,制动钳支架的7阶振动模态是导致制动噪声产生的原因之一。对制动钳支架结构设计进行了改进,并对装有改进后制动钳支架的盘式制动器进行了台架试验。结果表明,制动器冷态制动噪声从100.5 dB下降为73.4 dB,达到了该车型对制动器噪声的限值要求。

| Abstract: | Bench test is made to a car disc brake,it is found in this test that braking noise frequency mainly occurs at 3 kHz.With FEA,vibration characteristic analysis is made to brake disc,brake caliper case,caliper bracket and friction pad.Test results indicate that 7-order vibration mode of brake caliper bracket is a major contributor of braking noise.Structure of brake caliper bracket is modified,and bench test is made to the disc brake with the modified caliper bracket.The results show that cold state braking n... |
