| 摘 要： | 利用磁流变液变阻尼和磁流变弹性体变刚度的特点,提出可应用于工程车辆座椅的磁流变阻尼器和磁流变弹性体并联的结构方案,建立5自由度的＂人体-座椅＂动力学模型。针对该模型运用改进的单神经元自适应PID控制策略,通过仿真验证座椅悬架和控制策略的有效性。仿真结果显示、基于磁流变变阻尼变刚度结构的座椅悬架较只基于变阻尼的座椅悬架振动减少约35%,有效地提高乘坐舒适性。

| Abstract: | According to the characteristics of magnetorheological（MR） fluids variable damper and MR variable stiffness elastomer,a structural scheme consisted both of them in parallel connection that could be applied to engineering vehicle seat was put forward,and a dynamic model of ＂human body-seat＂ system with five DOF was established.With the application of the improved single neuron adaptive PID control strategy,the effectiveness of the seat suspension and the control strategy was verified through simulation.The results showed that the vibration of seat suspension with both variable damping and changing stiffness reduced by about 35%,which could improve the ride comfort effectively compared with the one based only on variable damping, |
