摘　　要：多功能人工关节模拟试验机是一台集机、电、液技术于一体的专用台架试验设备。该试验机的设计主要包括液压加载部分和机械部分的设计。液压加载部分设计的主要目的是产生正弦的压力波,从而与人行走时的脉动压力相一致,并且设计的液压加载部分的四个工作单元是独立工作,互不影响。机械部分包括四个独立的工作单元,可分别进行不同形式的人工关节摩擦磨损试验。本试验机的研制对人工关节的研究工作具有实际意义。The tester for simulating artificial joints is an appn）priative pedestal equipment which involves mechanism, electricity and hydraulic. The design of this machine includes hydraulic part and mechanism part. The main aim of the design of hydraulic load part is bringing sine pressure wave. So that it is consistent with the pulsation pressure bridged when human is walking and work cell of hydraulic part can work independently and do not impact on others. Mechanism part includes four work cells which can be used for experiment of friction and wear on artificial joint. This design is important for artificial joint.
