为实现对指接材端压范围的预测，采用ANSYS有限元分析软件模拟分析了樟子松结构用指接材3种嵌合度条件下的指接端压范围。结果表明：当指榫嵌合度为0、0．1、0．3 mm时，模拟分析得出的樟子松结构用指接材指接端压范围分别为1．5～3．0 MPa、2．0～3．5 MPa和2．5～4．5 MPa。将实验测试结果与模拟分析结果对比发现，模拟分析得出的指接端压范围相对试验测试结果小，但可以用于预测樟子松结构用指接材最佳端压取值。模拟分析与实验测试结果均表明，樟子松结构用指接材端压最佳取值为3．5 MPa。

By using the software of ANSYS for finite element analysis, the end-pressure range of Pinus sylvestris L. finger jointed lumber for structural use under three different fitness ratio were modeled. According to the modeling results, the end-pressure range were 1?5-3?0 MPa, 2.0-3.5 MPa and 2.5-4.5 MPa respectively when the fitness ratio are 0, 0?1 and 0?3 mm. Comparing the modeling results with the experimental results, it indicated that the end-pressure range from the modeling result was narrower than that of the experimental results. Therefore, the modeling can be used to predict the optimum end-pressure for finger jointed lumber, which showed that the optimal value of Pinus Sylvestris L. finger jointed lumber for structural was 3?5 MPa.
