摘要： 针对磁流变半主动悬架存在的控制策略设计和磁流变阻尼器逆模型求解复杂繁琐的问题，采用天棚控制、SHADD控制和频域控制3种典型的开关控制策略，基于具有并联旁通孔的磁流变阻尼器，在1/4车辆悬架试验台上进行半主动振动控制对比试验。结果表明，具有并联旁通孔的磁流变阻尼器与开关控制策略相结合可有效地抑制悬架振动，且控制过程简单，具有较好的实际应用价值。

Abstract: Aiming at the complexities of control strategies design and the inversemodel solution of magnetorheological (MR) damper in MR semiactive suspension, three typical switch control strategies, i.e. skyhook (SH) control, SHADD (acceleration driven damper) control and frequency domain control (FDC) are adopted to conduct a contrastive test for semiactive vibration control on a quarter vehicle suspension test bench based on a MR damper with parallel bypassing orifices. The results indicate that switch strategies combining with the special MR damper can effectively suppress suspension vibration with simple control process, having a good practical application value.
