摘　　要：本文针对步行器助行过程中上肢力提取问题,研制了一套上肢力提取系统,阐明了该系统的工作原理。通过对六维力传感器的线性和非线性标定和校准实验,对实验结果的分析表明了该标定系统设计及非线性标定方法的正确性和实用性。In order to effectively extract the information of the upper limb during walker-assisted walking, an extracting information system of the upper limb was developed. The operating principle of this system was illustrated. The results of relevant linear and nonlinear calibrating experiments on six- dimendiona force sensor showed that this system had the correct design and calibrating methods, and the nonlinear calibrating methods was practical.
