中文摘要：

为了实现管状机织物与管子之间摩擦系数的测量，设计了一套管状机织物在管子上抽拔过程的摩擦系数测量系统。首先通过施加弹性元件的方法，在实际使用工况下测试出附加摩擦力，再测试计算出弹性元件在圆管上产生的正压力，根据计算公式μ（摩擦系数）=F（摩擦力）／N（正压力）直接计算出摩擦系数；同理，通过弹性气压法测出管织物与管内壁的摩擦系数。然后使用所测量的摩擦系数在LS—DYNA分析软件中建立有限元模型进行计算，并与试验数据进行对比分析。最后，针对该摩擦系数测量系统在探月三期工程中月壤钻进取芯组件上的应用效果进行了实验检测与仿真计算对比。结果表明该系统测得的管状机织物在管子上抽拔过程的摩擦系数准确可靠，为有限元分析模型中摩擦系数的确定提供了一种有效的测量方法，满足月壤取芯组件的应用要求。

英文摘要：

To obtain the friction coefficient between the tubular woven fabric and the pipe, a measurement system of friction coefficient during the process of pulling tubular woven fabric out of the pipe is designed. Firstly, by applying the elastic＇ element, the additional friction can be acquired in the practical application. The vertical pressure generated by the elastic element on the tube can be obtained, which will be used to calculate the friction coefficient according to the formula μ （ friction coefficient ） = F （ friction ）/N （ vertical pressure）. In the same way, the friction coefficient between tubular woven fabric and the inner wall of the pipe can be acquired by the method of elastic gas pressure. Secondly, the friction coefficient measured by the system is utilized by the finite element model in the LS- DYNA software. The comparative analysis with testing data is also can-led out. Finally, the performance of the measurement system is analyzed and tested in the lunar soil coring components of the third stage of Chinese lunar exploration project. The simulation and experiment results prove that the friction coefficient measured by the system during the process of pulling-out between the tubular woven fabric and the pipe is accurate and reliable. The proposed measurement method to determine the friction coefficient in the finite element analysis model is effective. The practical requirements of the lunar soil coring components can be satisfied.
