采用不同长度的杉木股线，在不同的自由落体距离条件下制作定向刨花板。对sugi OSB的股向和力学性能进行了评价。所得结果可总结如下。自由落体距离和链长对取向角分布有较大影响。采用带浓度参数的von Mises分布函数，发现角的标准差可以作为预测分布的一个指标。蒙特卡罗模拟结果表明，理论计算结果与实验结果基本一致。测定了纱线长度和层状结构对其力学性能的影响。在25%的面层比下，弯曲性能在两个方向上是相等的。面内振动法得到的杨氏模量与面层比呈近似线性关系。内部粘结强度、板剪切模量和抗钉性能没有显著差异或只有轻微差异。需要进一步的研究。
Oriented strand boards (OSB) were made using sugi wood strand with different lengths at different free fall distance conditions. Strand alignment and mechanical properties of sugi OSB were evaluated. Results obtained can be summarized as follows. The alignment angle distribution was greatly affected by both free fall distance and strand length. It was found that the standard deviation of the angles can be a measure for predicting the distribution when employing the von Mises distribution function with concentration parameter. The Monte Carlo simulation showed an agreement between the theoretical considerations and the experimental results on the strand alignment. The mechanical properties as affected by both strand length and layer structure were determined. Bending properties could be equal in both directions at 25% face layer ratio. Young's modulus obtained by the in-plane vibration method showed almost linear relation to the face layer ratio. No significant differences or only a slight difference was observed for the internal bond strength, plate-shear modulus, and nail resistance properties. Further studies are necessary.
