摘要
结合人机工程学,以人体步态轨迹为基础,设计了基于四杆机构的下肢康复机构,并辅以减重与控制系统。依据正常人体步态轨迹确定凸轮轮廓及机构杆长,以人体五十百分位尺寸确定了起坐机构始末位置。对机构进行了运动仿真,仿真结果验证了机构设计的合理性。该机构结构简单,操作方便,具有一定的推广应用价值。
Combining with ergonomics, based on the human gait trajectory, the lower limb rehabilitation mechanism based on four-bar mechanism is designed, supplemented by weight loss and control system. According to the normal human gait trajectory, the cam profile and the length of the mechanism rod are determined, and the starting and ending positions of the sitting mechanism are determined by the human body's 50 percentile size. The kinematic simulation of the mechanism is carried out, and the simulation results verify the rationality of the mechanism design. The structure of the mechanism is simple and easy to operate. It has certain application value.
