摘 要 ：试验表明:刀片刃角β、刀片滑切角α、切割速度v及果柄直径d是影响果柄切割阻力P的主要切割参数。本文采用二次回归旋转组合设计法,通过对油松果柄切割阻力进行的室内试验,建立了油松果柄切割阻力的数学模型P=f(β、α、v、d);进而对切割参数进行了优化,为合理设计切割式球果采摘机具提供了理论依据。

Abstract:The pratical test indicated: There are many factors affecting cutting resistance of the blade edge, such as, angle of wedge β, angle of slidecutting α, velocity of cutting v and diameter of corm d. Through the indoor test of cutting resistance of the corms of Chinese pine, an regression formula P=f(β,a,v,d) is established by combinative designed method of quadratic-turning-regression. Then, the paper makes an optimization on the cutting parameters and provides a theoretical basis for designing a cutpicking device.
