膝关节前交叉韧带与内侧副韧带粘弹性实验研究

Experiment study on viscoelasticity of anteror cruciate ligament and medial collateral ligament of knee joint

目的研究了新鲜成人尸体膝关节前交叉韧带和内侧副韧带的粘弹性力学性质,为临床提供生物力学参数依据。方法对前交叉韧带和内侧副韧带进行应力松弛,蠕变实验。结果对实验数据进行归一化处理,得出了归一化应力松弛函数,蠕变函数,以回归分析的方法处理实验数据,得出了回归系数和拟合曲线。结论内侧副韧带7200s应力松弛、蠕变量小于前交叉韧带。对实验结果进行分析讨论。

Objective To make the raseamh on the biomechanical properties and viscoelasticity with fresh adult corpse to provide the biomechanics parameters for clinic. Method The stress relaxation and creep tests were made. Result The reduced stress relaxation function and creep function were obtained by maldng the experimental data normalization and then using regression analysis to obtaine the coefficient and fitting curve. Conclusion The quantities of stress relaxation and creep of MCL are lower than that of ACL in 7200s. The experimental results were analyzed and discussed.
