【摘要】 为缓解假肢佩戴者在运动过程中产生的冲击力,建立可压缩的倒立摆模型的运动微分方程,对磁流变阻尼器的粘滞性阻尼系数进行理论计算,并对三种不同运动状态下装有磁流变阻尼器和装有软硅橡胶的J型假肢进行模拟仿真,得到磁流变阻尼器在运动过程中的缓冲减振效果要比软硅橡胶更好,可为阻尼缓冲型运动假肢的研制提供参考。更多还原

【Abstract】 In order to alleviate the impact force on prosthesis wearer generated in the process of movement,the motion differential equation of the inverted compressible pendulum model of the J-artificial limb was established,and the viscosimetric-damping-factor of magneto-rheological damper was computed.Meanwhile,the simulation between magneto-rheological damper and soft silicone rubber in J-artificial limb under three motion conditions was conduced.The simulation results show that the magneto-rheological damper in the process of movement has better buffering performance that of soft silicone rubber.The study can offer references for the development of new buffer-type damping sports artificial limb.更多还原
