为了兼顾外骨骼动力的线性输出与穿戴过程的安全性,设计了一款包含助力与缓冲两种工作模式的下肢外骨骼。首先,对外骨骼膝关节缓冲器及整机模型进行了参数计算与结构设计;然后,对其做动力学分析并通过Matlab计算得到关节理论力矩;将计算所得参数与理论力矩分别代入Adams,对两种工作模式下的外骨骼进行仿真试验;通过对比仿真结果与人体运动标准数据,证明外骨骼助力模式可基本满足穿戴者正常行走需要,缓冲模式可在突发状况下缓冲刚性冲击。研究结果为后期系统的控制与模型制造提供了重要的理论依据。
In order to balance the linear output of the exoskeleton power and the safety in the wearing process, a wearable flexible knee joint exoskeleton with two working modes of power assist and buffering is designed. Firstly, the parameter calculation and structural design of the knee bumper and whole machine model of the exoskeleton are carried out. Then, the dynamics analysis of the joint is carried out and the theoretical moment of the joint is calculated by Matlab. Finally, the calculated parameters and theoretical moments are substituted into Adams to simulate the exoskeleton under the two working modes. By comparing the simulation results with the human motion standard data, it is proved that the exoskeleton assist mode can basically meet the wearer's normal walking needs, and the buffer mode can buffer the rigid impact under sudden conditions. An important theoretical basis for the subsequent system control and prototype manufacturing is provided.
