    摘要:

    分別以糙米的腹部、背部作為承壓面，對糙米的三點彎曲破碎力學性能進行了測試。測試結(jié)果表明，籽粒腹部、背部的三點彎曲破碎力和破碎力的分布特性存在一定的差異性，即腹部作為承壓面的破碎力分布區(qū)域較分散，呈現(xiàn)多峰分布，而背部作為承壓面的破碎力呈現(xiàn)集中分布的特性；腹部作為承壓面的抗彎強度和彈性模量均大于背部，而其斷裂能卻小于背部。糙米的加工品質(zhì)與其三點彎曲破碎力學性能之間亦存在一定的相關(guān)關(guān)系。

    Abstract:

    Three-point bending breaking force for ventral and dorsal side of brown rice was measured individually. Average kernel breaking force (the force required to break a brown rice kernel in three-point bending) between ventral side and dorsal side were different, and kernel-to-kernel breaking force distributions were also quite different. The breaking force distribution for ventral side tended to be multi-peak, but that for dorsal side tended to be single-peak. The bending breaking strength and elastics modulus for ventral side were more than those for dorsal side, but the fracture energy for ventral side was less than that for dorsal side. On the other hand, the rice processing quality indexes were correlated to the mechanical properties of rice.
