【摘要】 对于大吨位和高驶速度的工程车辆,普通减振系统己不能满足车辆振动舒适性的需要,振动控制研究是设计开发新一代工程车辆、提高舒适性的重点问题。针对工程车辆悬架系统的振动特点,为了行驶平顺性和保证系统安全性,提出建立适用于工程车辆振动控制的新型自适应控制器,简化的车辆模型和自适应滤波算法。仿真结果表明,簧载质量加速度的均方根值降低23%,悬架系统动挠度均方根值降低33%,工程车辆的乘坐舒适性得到明显改善,为设计提供可靠依据。更多还原

【Abstract】 For heavy-load and high-speed engineering vehicle,the general suspension damping system has not met the needs of vehicle riding comfort.Study on vibration control is one of the key issues in order to design a new generation engineering vehicle and improve its riding comfort.Based on a simplified engineering vehicle model and adaptive filtering algorithm,a new adaptive controller for vibration control of engineering vehicle is designed.Simulation results show that the RMS value of the sprung mass acceleration reduces by 23%,and the RMS value of suspension dynamic deflection reduces by 33%.The riding comfort of engineering vehicle has been significantly improved.更多还原
