| 摘 要： | 建立了一个针对高危女性人群股骨结构的三维有限元模型,分析了运动荷载作用下此类股骨的应力和应变分布以及股骨破坏的可能部位.结果表明:运动荷载使股骨产生较大的横向位移和弯曲变形;股骨颈处的应力和应变最大,容易在股骨颈处以及大转子与股骨干的连接部位附近发生破坏.模拟结果为研制适用于此类人群的高性能人工股骨提供了参考.

| Abstract: | A 3D finite element model for the high-risk broken sensitive femurs of female adults is built on basis of the ANSYS code.The stress and strain distributions and the domains where the breaking might take place are computed and analyzed with this model.It indicates that the external loads due to the motion on the femoral head cause a considerable lateral deformation to the femoral shaft and a bending deformation.The maximum stress and strain are at the femoral neck.The femoral neck and the neighborhood area connecting the greater trochanter and femoral shaft are weak areas which it is easier to fracture under the external loads. The simulation provides some insight for understanding and developing the proper artificial femur for these female groups. |
