Abstract:

The adjustable shock absorber of semiactive suspension was developed. On the basis of the project analysis, the structure of adjustable shock absorber was presented. And the samples were manufactured and the bench test was made to obtain velocity characteristic. The absorber samples and the data acquisition system were fixed in the target vehicle, and the road tests were made. The results indicate that the adjustable shock absorbers can retrain body pitch vibration during urgent braking maneuver effetively.

Key words: vehicle engineering, semi-active suspension, adjustable shock absorber, velocity characteristic
