碩士 === 國立中興大學 === 機械工程學系所 === 98 === The 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.
