| 摘 要： | 根据自然骨组织的微观结构特点,建立了一种圆柱状骨支架模型,它由圆环骨板、变截面圆杆和变截面孔洞组成.其中变截面圆杆将圆环骨板连接起来,变截面孔洞使骨板连通.通过胞元力学模型分析得出,胞元旋转角度呈0°排列较好;当圆杆和孔的直径减少和数量相应增加时,胞元的最大等效应力相应减小. |

| Abstract: | According to the characteristics of the microscopic structure of bone tissue,a cylinder-shaped bone scaffold is established.It consists of ring plates and variable cross-section rods and variable cross-section holes,and the ring plates are connected by variable cross-section rods and variable cross-section holes.By the unit cell finite element model analysis,the bearing capacity of the unit is better at 0 ° rotation angle.When the rods and the holes diameter decrease and their numbers increase,the maximum equivalent stress get lower accordingly. |
| Keywords: | bone tissue engineering bone scaffold model gradient holes |
