| 摘 要： | 为了研究木薯秸秆冲击韧性的指标影响因素,利用MW-4木材万能试验机,并选取木薯秸秆的品种、放置时间、碰撞部位作为影响因素,对木薯秸秆进行正交冲击试验。结果表明:品种对冲击能量的影响最大,当品种为SC6、放置12d、碰撞部位为上部时冲击能量最小;同时,品种对冲击韧性的影响也最大,冲击韧性最小的组合是品种为SC6、放置0d、碰撞部位为下部;木薯秸秆下部的平均冲击能量和冲击韧性均大于上部的。

| Abstract: | In order to study the factors that the influence of the cassava stalk toughness. Orthogonal experiments were used to test cassava stalk with MW-4 universal testing machine And the influencing factors were selected, for cassava stalk variety, placed time, and colliding parts. The results show that: effect of varieties on the impact energy is the largest, while, the impact energy was the smallest when the variety is SC6, placed for 12 days, and the the upper part collision site. Effect of varieties A on the impact toughness is the largest. The impact toughness is the smallest when the variety is SC6, the moisture content is placed for 0 days, and lower part collision position. The average impact energy and impact toughness of the lower part of cassava stalk are higher than the upper part. |
