【摘要】 在改装后的摆锤式试验台上，进行了三个玉米秸秆揉切特性的试验。试验一．动定刀间隙及动刀滑切角对揉切能耗和揉丝效果的影响，这是一个三因素正交试验，得出滑切角对能耗影响不显著的结论。为了验证此结论，又作了试验二．滑切角单因素对揉切能耗和揉丝效果的影响，此试验验证了第一个试验的结论。另外，试验三．秸秆含水率及其生长部位对揉切能耗和揉丝效果的影响，考察了秸秆本身特性对指标的影响程度。 试验中，在LabWindows/CVI软件开发平台下，开发了用于测量能量消耗的虚拟仪器，此仪器可计算能耗、速度并显示其数值和相关曲线。 本论文的研究可为今后小型秸秆揉搓类机具的设计提供理论指导和参考数据，同时也可为进一步进行试验研究提供试验思路和测试方法。更多还原

【Abstract】 Three experiments on the cuffing and rubbing properties of corn stalk have been conducted on a pendulum test-bed. The main item investigated in the experiments was energy consumption caused by cutting and rubbing stalk, and the stalk status after processing was also an item. The first experiment was a multifactor orthogonal test. Suitable slip cutting angle and clearance between movable blade and stationary blade have been found. To testify the conclusion got from the first experiment, the second test studied on the effect of the slip cutting angle on the items. It was a single factor test. The last tested how the characteristics of the stalk itself affect the items. A virtual instrumentation to measure energy consumption was developed by the software development platform called Lab Windows/C VI. The results got from above experiments provided the guide in theory and referential data for further designing cuffing and rubbing machine, at the same time, more clues and test ways for further experiment research have been indicated.更多还原
