Abstract

The invention relates to the technical field of auto parts test, and especially relates to a magnetorheological damper performance test device. The magnetorheological damper performance test device comprises a power device, a guide mechanism, a force sensor, and a displacement sensor. The power device is used for making a to-be-tested magnetorheological damper do reciprocating motion along the guide direction of the guide mechanism. The force sensor is used for detecting damping force information generated by the to-be-tested magnetorheological damper when the to-be-tested magnetorheological damper does reciprocating motion. The displacement sensor is used for detecting displacement information of the to-be-tested magnetorheological damper when the to-be-tested magnetorheological damper does reciprocating motion. The performance test device has a diversified test function, can meet the excitation-adjustable test requirement of magnetorheological dampers, and has test inclusiveness to magnetorheological dampers of different models.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a performance testing device for a magneto-rheological shock absorber. Background technique [0002] The magnetorheological shock absorber is a new type of intelligent shock absorber with online adjustable damping force. It utilizes the non-Newtonian rheological properties of magnetorheological fluid under a magnetic field, and can adjust the damping of the shock absorber in real time according to different working conditions to improve the comfort and handling stability of the vehicle. Due to its superior damping adjustment, fast response, good reliability, and low energy consumption, the magneto-rheological shock absorber is used in the field of vibration control and vehicle body roll stability control with the help of semi-active suspension. More and more applications. [0003] In the research and development of vehicle anti-rollover control system using magnetorh...
