中文摘要：

根据人工关节材料的体外磨损性能测试，开发了一种新型复合运动销盘测试装置（MPOD）。借助公理化设计原则，分析了仪器中不同功能之间的关系。根据独立公理生成了相应的设计矩阵，并在非耦合设计矩阵的基础上进行模块化开发，包含运动合成模块、销导向模块及加载模块。通过销传导模块中的力传感器可对试验中的摩擦力进行测量。

英文摘要：

A new multidirectional motion pin-on-disk apparatus, MPOD, was designed, built and validated for the wear testing of artificial joint biomaterial. Following axiomatic design principle, the relationships of different functions of MPOD were ana- lyzed. Then, MPOD, consisting of motion generation module, loading module and pin guiding module, were designed accord- ing to the uncoupled design matrix. On-line friction measurement can be realized by using the force sensors assembled in the pin guiding module.
