摘　　要：当前国内外医用牵引床控制模式通常采用单片机-电气-机械的结构形式,该模式存在驱动平稳性差、设置复杂、结构质量大、误差大、噪声大等问题。为此,设计了新型的通过计算机闭环控制系统及双液压缸控制系统实现控制的医用牵引床。分析了系统工作原理及结构构成,研究了计算机闭环控制系统框架及双液压缸液压系统工作原理。该设计实现了牵引床的旋转、倾角、摆角、牵引动作多功能控制。所设计牵引床降低了控制中的噪声及振动,控制过程平稳、控制精度高,从主观和客观上均弱化了患者使用中的疼痛感,提高了患者治疗过程中的舒适性。At present,the control mode of medical traction bed at home and abroad usually adopts the structural form of single chip microcomputer electrical machinery.This mode has some problems,such as poor driving stability,complex setting,large structural quality,large error,large noise and so on.Therefore,a new type of medical traction bed controlled by computer closed-loop control system and double hydraulic cylinder control system is designed.The working principle and structure of the system are analyzed,and the framework of computer closed-loop control system and the working principle of double hydraulic cylinder hydraulic system are studied.The design realizes the multi-functional control of the rotation,swing angle,inclination and traction action of the traction bed.The traction bed reduces the noise and vibration in the control,and the control process is stable.The control precision is high,which weakens the pain of patients subjectively and objectively,and improves the comfort of patients in the treatment process.
