Design of Abnormal Noise Identifying System for Suspension Shock Absorbers
摘要
Abstract
The abnormal noise problem of a vehicle’s suspension shock absorber was studied. The road test and rig test of the vehicle were carried out. By collecting a large amount of research data, a method of clustering analysis based on weight coefficient was processed for identifying the abnormal noise of the suspension shock absorber. The principle of this method was analyzed. Moreover, based on the virtual instrument development system LabVIEW and the toolbox of signal processing in MATLAB, a test system for identifying the abnormal noise of the suspension shock absorber was developed and applied to the shock absorbers. The test result shows that the correlation coefficient between the identification results and the subjective evaluation in road test is higher than 0.92, which can meet the product quality control requirements of most factories and enterprises. This work has provided a reference for sample test, improving identification reliability and production process modification.关键词
