摘要
传统的被动剪式座椅减振阻尼单一,不能保证商用车行驶在不同工况下都具有良好的舒适性。为了主动的适应商用车复杂多变的行驶环境,提高商用车乘坐舒适性。文章建立了剪式座椅悬架的ADAMS模型,并根据ADAMS模型的结果建立剪式座椅悬架的简化模型,根据最优控制理论和模糊控制方法设计悬架的半主动控制算法。通过与被动座椅簧上质量加速度对比可知,半主动控制算法能够显著提高剪式座椅悬架的舒适性。
Passive seat can＇t meet the requirements of better riding comfort in different driving conditions, because the absorber has single damping. This paper introduces a kind of seat semi-active suspension control method, which can adapt to the complicated driving environment of commercial vehicle and improve the riding comfort of commercial vehicle. Firstly. according to the specific structure of scissor seat suspension, the simulation model of the scissors seat suspension is established in ADAMS environment. Then. according to the simulation results of ADAMS model, a simplified model of the suspension is obtained. According to the optimal control theory, and fuzzy control method, the semi-active control algorithm is designed. Finally, by comparing the sprung mass acceleration signal with the passive seat, the semi-active control algorithm can significantly improve the comfort of the scissor seat.
