Abstract

The invention discloses a shock absorber abnormal sound test bed which comprises a vibration exciter connected with the upper end of a shock absorber, and a tray device connected with the lower end ofthe shock absorber and used for adjusting the distance between the lower end of the shock absorber and the vibration exciter. According to the shock absorber abnormal sound test bed, the abnormal sound condition of the vehicle shock absorber can be observed in a short distance, engineers can identify and solve problems conveniently, the working efficiency can be improved, the device principle issimple, the input cost is low, the abnormal sound identification speed is high, and the labor cost and the material cost are further reduced.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular, the invention relates to a shock absorber abnormal sound test stand. Background technique [0002] With the rapid development of China's economy, the automobile industry is also booming, and the direction of consumers' attention to automobiles is gradually changing. From the reliability of vehicles in the early stage to the change in comfort at the present stage, in terms of vehicle comfort, the whole vehicle Abnormal noise is one of the most concerned points. According to incomplete statistics, vehicle abnormal noise accounts for more than 40% of the quality problems in the entire market, seriously affecting consumers' influence on vehicles and the attitude of vehicle brands. [0003] Among the abnormal noise problems of the whole vehicle, the abnormal noise of the chassis occupies a large part, among which the abnormal noise of the vehicle shock absorber is more prominen...
