本研究首先針對有關腹部訓練之運動器材做專利以及相關文獻的搜索,再依據使用者在運動時不同的肢體動作、發明年代與發明人所屬國家加以分類,以便從專利分類中找出創新設計與發展的方向,即是結合了上身擺動、腹部伸展與擠壓之三種動作,以期擁有一機多用的功能。在根據成本、安全性與舒適性的考量下,藉由機構合成,盼能找出符合設計條件的雙自由度五連桿運動鏈,並由人體計測資料庫來訂定相關重要尺寸,以確保本研究之設計與整體運動過程皆符合人因工程條件,才能保證使用者在運動過程中不會受到不必要的運動傷害。接續透過電腦輔助繪圖軟體Pro/Engineer Wildfire 3.0建立腹部訓練機之3D模型,並確認其桿件間無干涉情況發生,最後再利用ANSYS 11.0電腦輔助分析軟體模擬一200kg使用者於不同模式時操作的應力分布情況,並以此為基礎製作出實體模型,以確保本研究綜合腹部訓練機之實際可行性。
The research features patents and literature on abdominal exerciser. We could achieve innovative design from classified patents which are sourcing by different exercising modes, years of invention and nationalities of inventors. It’s a combination of three motions with multiple functions. For cost, safety and comfortable concern, we try to use a five-bar linkage which has two degree of freedom mechanism through mechanism syntheses. To avoid unnecessary injury during exercising, we define several crucial dimensions by a data bank of human body and ensure they match human-factors engineering. In addition, create abdominal exerciser 3D model by CAD software (Pro/Engineer Wildfire 3.0), and check that is no conflicts between linkages. The last, CAE software (ANSYS 11.0) could be used for analyzing stresses distributed in different modes. This research is used as a full-scale model. These are ways to prove the feasibility of abdominal exerciser.
