摘　　要：为了准确测试出"无摩擦"活塞气缸在运动过程中所受到的微小摩擦力,提出一种基于磁场力的非接触式的微小摩擦力测试方法,并设计了测试装置。该方法利用磁场之间的作用力推动被测件,实现了非接触式测量。此外,建立了磁场仿真模型,理论上验证了该测试方法的合理性。The design of a micro friction force testing device to accurately examine the micro force was presented in the movement of frictionless pneumatic cylinders, which used a non-contact measuring method based on magnetic field force. This method made use of the force between two magnetic fields to push the measured pieces and achieved the goal of non-contact measuring. In addition, a magnetic filed simulation model was built, which theoretically verified the rationalization of this measuring method.
