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。
In order to alleviate the impact force on prosthesis wearer generated in the process of movement, the mo- tion 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 betweenmagneto-rheological damper and soft silicone rubber in J-artificial limb under three motion conditions was con- duced. The simulation results show that the magneto-rheological damper in the process of movement has better buff- eting performance that of soft silicone rubber. The study can offer references for the development of new buffer-type damping sports artificial limb.
