Abstract:
The work principle and abnormal noise test method of hind vehicle hydraulic shock absorber are analyzed, Based on experiment data and signal character analyse ,a test method is found to distinguish the abnormal noise of rear hydraulic shock absorber. Practical validates that the reliability rate of this test method can be over 98 percents, and it can be satisfied with the request of the factory. At last, the reason of abnormal noise is analyzed and simulated, the reason of different signal attenuation is explained, and the research conclusion is educed.
