摘要

为了减少运动过程中膝关节损伤的影响和能量消耗，根据人体工程学和人体下肢步态的特点，提出了一种无动力外骨骼。该装置由双弹簧机构辅助，并与膝关节平行佩戴。人体的代谢能量通过补偿下肢负功的能量损失而减少。同时，在ANSYS软件中对弹性储能元件进行仿真分析，确定储能单元尺寸与应变能的对应关系，从而实现储能单元的参数匹配设计与应用。最后，通过对肌电数据和人体膝关节扭矩数据的分析，验证了外骨骼的有效性。实验结果表明，该外骨骼具有良好的辅助效果，可以达到日常辅助行走的目的。

Design and analysis of a passive knee assisted exoskeleton

In order to reduce the impact of knee injury and energy consumption during exercise, an unpowered exoskeleton was proposed based on the characteristics of ergonomics and human lower limb gait. The device is assisted by a double spring mechanism and worn parallel to the knee joint. The metabolic energy of the human body is reduced by compensating for the energy loss the lower limbs negative work. At the same time, the elastic energy storage element is simulated and analyzed in ANSYS software, and the corresponding relationship between the size of energy storage unit and strain energy is determined, so as to realize the parameter matching design and application of energy storage unit. Finally, the effectiveness of the exoskeleton is proved by analyzing EMG data and human knee torque data. The experimental results showing that the exoskeleton has a good assistant effect, and can achieve the purpose of daily walking assistance.
