Research on Damping Characteristics of Lateral Semi-active Damper Contolled by Electro-hydraulic Proportional Relief Valve

对电液比例溢流阀控式横向半主动油压减振器的阻尼特性进行了理论研究,阐明该减振器的阻尼特性为速度平方型加可调的卸荷特性,指出调节电液比例溢流阀的溢流压力可以实现阻尼力的适时调整,而改变节流阀节流面积能够满足对最大被控阻尼力的不同要求。

The damping characteristics of lateral semi-active damper controlled by electro-hydraulic proportional relief valve are researched in theory.It is illustrated that the damper＇s damping characteristics are the square of the speed plus the adjustable unloaded characteristics.It is pointed out that the damping force can vary timely with regulating cranking pressure of the relief valve, and by changing the throttling area of throttle valve can satisfy the different need of the biggest controlled damping force.
