【摘要】 本文对松籽的几何特性进行了研究,建立了统一的几何模型。根据松籽脱壳前受力及变形状态,建立了松籽力学模型。通过分析确定了受力状态下松籽外壳可能断裂的方位,从理论上推得松籽崩壳的主要方式。为松籽脱壳机研究提供了依据。更多还原

【Abstract】 In this paper, the geometric character of pine-nutwas studied and an unified geometric-model is finded, andthen it’s mechanic-model is finded according to the forcing-forming statement whem pine-nut breaks. The possiblebreaking direction-position of the shell forced obtained andthe main ways whuch the shell will break is infered in theory.so that this paper provide the basis for the research ofpine-nut sheller.更多还原
