| Abstract: | An orifice type adjustable damper is designed on the basis of the passive hydraulic shock absorber of the original car, adjustable damping shock absorber performance analysis to derive the stepper motor and orifice mathematical relationship, both tension and compression stages of the force - velocity characteristics for shock absorber, meanwhile the improved sample of the adjustable damping hydraulic shock absorber is tested on the bench. The test results show that the adjustable damping shock absorber damping force curve is full of smooth without distinct distortion, the damping force changes motor. The designed adjustable damp with the opening changes of the orifice, which is corresponding to the angle of step ing hydraulic shock absorber basically meets the requirement. |
