摘要
建立了下肢假肢气压膝关节机构在站立相单腿承重工况下的三维有限元计算模型。通过 ADINA有限元分析软件的计算 ,表明该机构在强度、刚度方面完全能满足要求。
A calculating model on three dimensional finite element is established in the situation where the lower extremity pneumatic knee mechanism stands on its single leg under stance phase An analysis is conducted by an ADINA three dimensional finite element software which shows that this structure could completely satisfy the requirements on its strength and stiffness
