摘　　要：将带附加气室的空气弹簧和磁流变减振器应用于剪式座椅中,推导了座椅悬架系统的传递函数。在MATLAB/Simu-link环境下建立了座椅悬架PID控制仿真模型,模型中的激励为座椅支承中心加速度。以HY—Z04型剪式座椅为基础,选用ContiTech公司的SK37—6型膜式空气弹簧和美国LORD公司生产的LORD—1005型磁流变减振器,以实测座椅支撑中心处加速度为激励,用座椅悬架PID控制仿真模型仿真研究了车辆以8km/h行驶时的加速度响应。研究结果表明:PID控制后的座椅加速度明显小于未加PID控制的座椅加速度。Air spring with an additional air chamber and magneto-rheological shock absorber had been applied into a scissors seat,transfer function had been deduced through differential equations of motion of this air suspension seating system.The PID control simulation model of this seat suspension had been established using MATLAB/Simulink.The excitation in this model is the acceleration of the seat bearing center.Take ContiTech＇s SK37-6-type membrane air springs,HY-Z04-type scissors seats and LORD-1005-type magneto-rheological shock absorber produced by LORD of USA as examples.The excitation is the acceleration of the seat bearing center.Automobile＇s response had been studied at speed of 8 km/h in the PID control simulation for driver＇s seat model.The results show that the acceleration of seat through PID control less than the one without PID control.
