dc.description.abstract物體飛落為相關重大職災中發生頻率最高的災害類型,發生意外的因素,包括吊具或鋼索強度不足、吊掛不當使用,若發生安全意外,更是造成無法挽回的遺憾,因此分析其塑性行為是有其必要性。 過去相關的研究,在有限元素分析在塑性分面,硬化參數往往都是以線性方式來計算,但實際上硬化參數是非線性變化。其他的研究以主要加強材料性質及相關材料處理方式進行分析。 本研究主要是研究機械吊具之結構,主要是透過材料實驗方式,得到吊具的材料性質,並以實驗資料建立硬化參數方程式,來表示硬化參數非線性行為,取代以往線性方式來計算硬化參數,並以塑性理論與有限元素法進行驗證此方法。並且依據實際使用的吊鉤及吊環,建立有限元素模型,進行彈塑性分析,再與吊鉤及吊環的拉伸實驗進行比對。研究結果顯示以此有限元素分析的結果與實驗,有相當高的吻合度,透過此方法可以精確了解吊具的應力分佈及變形情況,以確定設計之可行性或擬定可能改善之方案。zh_TW
dc.description.abstractThe fallen object is most serious occupational accident happened frequently than others in terms of clarification, including insufficient strength of hook and wire rope. To hang the hook improperly usually causes accident that we regret and cannot be recovered in a short time. Therefore, it is critical to analyze inelastic material behavior of the hook. In the study of the past,when it comes to elasto-plastic analysis, strain-hardening coefficient is calculated by the method of linear. However, elasto-plastic analysis did not vary by the finite element method that had used the constant for but in fact strain-hardening coefficient is variable. The other research is to enhance the analysis of strength increase and the method of material treatment. This research is mainly to study the structure of the mechanical hoist that mainly has follow material experiment to obtain unknown materials properties, and create strain-hardening coefficient equation by the experiment materials. The equation is the nonlinear of method that had replaced the linear of method in the past. The method is verified by plasticity theory and finite element method.We make two finite element models from hook and Hoist Ring,The next step is to compare elasto-plastic analysis with experiment and the consequence has to be in correspondence to each other. If we use the method, we will accurately understand distributed stress and deformation to ensure the feasibility of the design or improved plan.en_US
