四大竹乡产毛竹弯曲力学性能的比较研究

A Comparative Study on Binding Performance of Moso Bamboo from Four Hometowns of Bamboo

对四大竹乡产毛竹的弯曲力学性能进行了研究,使用电子万能力学试验机采用径向加载方式测试竹材弯曲强度(M OR)和弯曲弹性模量(M OE),并比较分析了毛竹弯曲断裂形态差异。结果表明:生长朝向和竹节对毛竹的弯曲力学性能具有较大影响;测量方式不同,毛竹的弯曲力学性能差异较大;四大竹乡产毛竹M OR差异较大,而M OE差异不明显。

In this paper,bending performance of Moso bamboo from four Hometowns of Bamboo was studied.MOR and MOE were tested with radial load by mechanics apparatus.Bending rupture of bamboo with and without node were comparatively analyzed.The results showed that aspect and node influence bamboo bending performance.In different measuring mode,the bamboo bending performance is different.In four counties under study,MOR is very different and MOE difference is not significant.
