摘要:	本研究針對落花生藤蔓與子房柄的物理性質及力學特性做詳細的探討，以做為設計開發落花生收穫機上的拔株機構的依據。利用萬能試驗機及流變試驗機分別量測落花生藤蔓的抗拉強度與抗剪強度及子房柄的抗拉強度；並且量測落花生藤蔓與碳鋼之間的動摩擦係數。實驗結果顯示，落花生藤蔓的抗拉強度與抗剪強度隨含水率的增加而降低，其變化範圍分別在 12.5 至 18.3MN/m ?暑P 9.6 至 22.5MN/m ?握孜﹛F 未經乾燥處理的子房柄的平均抗拉強度為 16.1MN/m ?插F落花生藤蔓與鋼板之間的動摩擦 Some selected mechanical properties of peanut stems and pegs were evaluated in laboratory to decide the parameters of designing a lifting mechanism for a peanut combine harvester.
