摘要:
为了研究车身振动对人体产生的影响,根据人-车-路系统之间的相互作用关系,建立二分之一人体-车辆-路面九自由度动力学模型.将一种多通道FxLMS自适应控制算法PM-MFxLMS应用于座椅振动主动控制中,在Matlab/Simulink中,建立人-车-路振动主动控制模型,并分别对被动控制、传统FxLMS算法和PM-MFxLMS算法的控制效果进行仿真对比.结果表明:低频振动(0~20 Hz)会导致人体产生共振,采用振动主动控制可以降低共振峰值,改善乘坐舒适性;与传统FxLMS算法相比,PM-MFxLMS算法具有较好的收敛性和稳定性.
Abstract:
In order to study the influence of vehicle vibration on the human body, half nine-degree-freedom dynamic model involving human-vehicle-road was established based on the interaction among elements in the human-vehicle-road system. A multi-channel FxLMS adaptive control algorithm PM-MFxLMS was proposed to the active control of seat vibration. The active control model of human-vehicle-road vibration was established in Matlab/Simulink. The control effects of passive control, traditional FxLMS and PM-MFxLMS were simulated respectively. The results show that low frequency vibration(0-20 Hz)will cause the human body to resonate. The active vibration control can reduce the resonance peak value and improve the ride comfort. Compared with the traditional FxLMS, the PM-MFxLMS algorithm has better convergence and stability.
