利用 MATLAB/Simulink 的油气悬架输出力分析
Analysis of output force characteristics of hydro-pneumatic suspension based on MATLAB/Simulink
摘要
Abstract
Based on the investigation of vibration characteristics of certain vehicle without suspension ,a new type of damping-ad-justable hydro-pneumatic suspension was put forward .Based on the analysis of working principle ,the nonlinear mathematical mod-el and output force characteristic model of suspension were set up .Using MATLAB/Simulink,through adjusting initialization pres-sure and volume of accumulator ,the diameter and number of orifice valve ,the diameter of adjustable throttle and the amplitude and frequency of excitation ,the influences of these parameters to output force characteristics were put forward .Simulation results show that initialization pressure of accumulator doesn ’ t influence the curve shape of displacement and velocity characteristics of output force and doesn ’ t influence the damping force of suspension ,and orifice valve ,adjustable throttle and excitation influence greatly to output force characteristics ,especially to revert phase .关键词
