【摘要】 设计了一种节流口可调式液压减振器,通过理论分析和阻尼特性试验,得出了阻尼力与步进电机转角之间的关系。在此基础上,设计了半主动悬架控制系统,建立了半主动悬架试验物理模型,并进行了半主动悬架系统试验研究。结果表明,设计的半主动悬架及其控制系统性能稳定可靠,其动态性能明显优于传统被动悬架。更多还原

【Abstract】 A kind of hydraulic damper with the throttle adjustable was designed.Based on theoretic analysis,these damping characteristic experiments of the damper were made,and the relationship between the damping force and the turning angle of a step electric motor was found.On this foundation,semi-active suspension control system was designed,and the semi-active suspension test physical model was established.And the performance of semi-active suspension and its control system were studied.It shows that the performances of semi-active suspension is steady and works well.It is excel that of traditional passive suspension in the dynamic performances.更多还原
