摘　　要：秉承"绿色、安全、创新、健康、共享"的设计理念,针对目前市场上主流的手动与电动颈椎牵引椅存在不能根据使用者个体差异提供最佳牵引力、牵引时间等问题,开发了一款由液压系统控制颈椎牵引过程自动化的共享型自动颈椎牵引椅。根据用户身体特质自动设定最佳颈椎牵引参数,提高对使用者的牵引效果,拓展设备的应用范围。通过Matlab软件对液压控制系统进行仿真,结果表明,液压控制系统对压力阶跃信号的响应灵敏、超调量小,能满足系统对快速性和稳定性的要求。Adhering to the design concept of"Green,Safe,Innovative,Healthy and Sharing",aiming at the problems that the current mainstream manual and electric cervical traction chairs could not provide the best traction force and traction time according to the individual differences of users,a shared automatic cervical traction chair controlled by hydraulic system is developed.It could automatically set the best cervical traction parameters according to the user’s physical characteristics,improved the user traction effect and expanded the application scope of the equipment.The simulation results show that the hydraulic control system could respond sensitive to the pressure step signal and the overshoot is small,which meets the requirements of the system for the rapidity and stability.
