含时滞天棚阻尼半主动悬架建模及稳定性分析
Modeling and Stability Analysis of Semi-active Suspension with Sky-hook Damper Coefficients Considering Time Delay
摘要
Abstract
In order to study the impact of time delay on the dynamic characteristics and stability of semi-active suspension with sky-hook damping,the 2-DOF mathematic model of semi-active suspension with time delay is first established,then the stability analysis method of the critical time delay of the semi-active suspension and the stability margin are presented based on stability theory.The critical time-delay value is solved by using numerical method,moreover,the critical time delay resulting in instability of the semi-active suspension and the stable areas for non-arbitrary and arbitrary time delay are obtained under various passive damping coefficients and the feedback gains of sky-hook damping coefficients.The simulation model of semi-active suspension with time delay is built,and the influence rules on dynamic performances and stability of the suspension are obtained.关键词
