Abstract目的:探讨采用工程材料力学中抗弯梁的力学模型,通过兔胫骨三点弯测试,获得整骨材料力学测试方法实用的力学参数。方法:采用10只正常成年大耳白兔下肢骨标本,共10对胫骨,行三点弯力学测试。作为骨的三维实体模型建立后,虚拟加载的一种实验对比模式。支承跨距为80mm。结果:得到10对正常大耳白兔胫骨抗弯力学参数。胫骨最大载荷所对应的加载点挠度平均值右侧(2.737±0.262)mm,左侧(2.739±0.233)mm;胫骨的最大载荷(代表抗弯强度)的平均值右侧(17.803±2.675)kg,左侧(18.366±2.653)kg;胫骨最大载荷前载荷-挠度曲线下面积平均值右侧(23.829±4.413)kg·mm,左侧(24.725±4.101)kg·mm;胫骨载荷 ̄挠度曲线线性部分斜率(代表抗弯刚性)平均值右侧(7.545±1.310)kg/mm,左侧(7.631±1.174)kg/mm。结论:正常家兔胫骨个体间差异较大,建议三点弯测试实验中采用双侧配对比较。
