雨傘收摺傘強調其收摺效果,而摺數越多收摺效果越佳,能使收摺後的長度更短。一般而言,收摺傘除了輸入桿上面用一滑動對之外,其餘都使用旋轉對,而目前在傘骨上使用滑動對的技術已經有所突破,但仍未有傘骨上使用滑動對的相關研究。本文將在傘骨上增加一滑動對,並針對Watt、Stephenson和八桿件十接頭之運動鏈,利用顏氏創造性機構構造設計方法,找出收摺效果較佳,抗風能力較好的構造設計。本研究提出數項配合判斷的規則,總共得到12種可行的機構構造,並進一步利用SolidWork和ADAMS軟體針對其中較佳的10種進行收摺效果與抗風能力分析比較,經由抗風能力與收摺效果評估,再從10種較佳的機構構造得到最後2種構造。
Folding umbrella features its folding effectiveness. The more the folding sections are the shorter and better after folded becomes. Generally speaking, besides the input slider, the folding mechanism applies all revolute joints. This thesis presents twelve novel creative folding mechanism designs obtained by using a sliding pair to Watt-type,Stephenson-type and eight-bar-ten-joint kinematic chains via Yan’s creative mechanism design method. Furthermore, the folding effectiveness and wind resistance have been simulated and analyzed by using SolidWorks and ADAMS software for ten of twelve novel conceptual designs, and the best two among them have been identified.
