摘要
用ADAMS软件建立双A臂悬架多体动力学模型,计算簧载质量速度及其变化率作为主动悬架控制的输出量;半主动悬架采用带修正因子的模糊控制器,用加权系数分别控制簧载质量速度与加速度所占模糊控制器输入的比重,其中加权系数采用簧载质量速度进行修正调节;在MATLAB搭建悬架系统联合仿真模型,计算结果表明:带修正因子的模糊控制器在各不同车速阶段对改善悬架的总体性能有明显作用,车身垂直加速度在低频阶段改善突出,提升整车在不同车速范围内乘坐舒适特性。
Using the ADAMS software,double wishbone suspension multibody dynamics model,Calculated sprung mass velocity and its rate of change as the active suspension control output; Semi-active suspension with fuzzy controller based on a correction factor,the weighting coefficients are controlled by the proportion of the sprung mass velocity and acceleration share fuzzy controller input,wherein the weighting factor using the corrected sprung mass speed adjustment; In MATLAB built suspension system co-simulation model,The re-sults show that： the use of fuzzy controller in various stages of vehicle speed to improve the overall performance of the suspension plays a significant role,Vertical body acceleration,stroke improvement prominent in the low frequencies,to enhance vehicle ride comfort charac-teristics in different speed ranges.
