Design and Validation of a CDC Damper with a Built-in Proportional Valve
摘要
Abstract
A continuously damping control(CDC)damper with a built-in proportional valve was designed and introduced,the damping mechanism was introduced and damping force simulation model was built.To validate the correctness of simulation model,the damping force-stroke characteristics and force-velocity characteristics were obtained through simulation and physical samples measurements.Results shown that,there is a good consistency between simulation and testing due to the deviation in damping characteristics is less than 10％.The damping force were decreased by the increasing of excitation current,and the change speed of this change trendy is from positive to negative.Force-velocity characteristics shown that the slope of damping curve increased before"knee velocity",but kept in linear after"knee velocity".Damping force can be tuned from 1544 N to 4914 N in rebound stroke,and tuned from-1415 N to-1937.7 N in compression stroke.关键词
