摘要:	本文研究針對不同形式電梯用繩索固定用安全零件，做應力分佈模擬以及分析，並記錄下來，後續再以實際實驗結果數據做比對。本研究僅適用特定廠商之電梯時使用，如需應用於不同場合時，請修改相應數據以符合該實驗之環境及設備。本研究分為兩大部分1.以鋼索拉伸實驗為依據，紀錄鋼索固定器的受力變化，並以30Hz低通濾波轉換成應力曲線圖求得最大點，依據3點最大點推測出最大應力點於錐套最小管徑處。2.以專業機械3D繪圖軟體繪製工程圖作為基礎，先依照工程圖分別繪製各個零件之零件圖，其中使用了疊層拉伸、填料、限制條件等功能還原出鋼索固定器的各部件安裝情形，在專業機械3D繪圖軟體的模擬程式模擬拉伸實驗過程中，1.經常因邊界限制條件狀況的不同而導致模擬不完全2.受力設定上，常常遇到受力不均以及位移錯誤等等狀況。最後，依模擬結果，統計4種錐套形式的應力及價格差異。本研究以電梯鋼索固定器為核心，透過實驗與模擬方法系統性地探討不同設計的應力分佈與性能差異。結果顯示，在最大應力方面，焊接式與包角式(無焊接)皆變差，分別為劣化12% 及1.6%。改良後的包角式錐套在應力分佈和製造成本上具有明顯優勢，分別優化1% 及65%，為傳統焊接式設計提供了可行的替代方案。本研究不僅驗證了改良設計的可行性，也展現出透過模擬分析在提升鋼索固定器安全性與效率上的具有關鍵作用。;This study focuses on simulating and analyzing the stress distribution of various types of safety components used to secure elevator ropes, with the results recorded and later compared with actual experimental data. The research applies only to elevators from a specific manufacturer. For applications in different environments, the relevant data should be adjusted to fit the specific conditions and equipment. The study is divided into two main parts: Based on tensile tests of steel ropes, the changes in force on the rope clamp were recorded. A 30Hz low-pass filter was used to convert the data into stress curves to identify the maximum stress points. The maximum stress was inferred to occur at the smallest diameter of the cone sleeve by analyzing three peak values. Using professional 3D mechanical design software, engineering drawings were created as a foundation. Individual component drawings were developed based on these engineering drawings. Features such as layered stretching, fillers, and boundary conditions were used to accurately replicate the assembly of the rope clamp components. During the simulation of the tensile test using the software, two main issues frequently arose: incomplete simulations due to variations in boundary conditions and problems with uneven force distribution and displacement errors.Finally, based on the simulation results, the stress distribution and cost differences among four types of cone sleeves were evaluated. This study centers on elevator rope clamps, systematically exploring the differences in stress distribution and performance across various designs through experimental and simulation methods. The results showed that in terms of maximum stress, the welded type and non-welded wrap-around type performed worse, increasing stress by 12% and 1.6%, respectively. However, the improved wrap-around cone sleeve showed clear advantages, with a 1% optimization in stress distribution and a 65% reduction in manufacturing cost, offering a viable alternative to the traditional welded design. This study not only verifies the feasibility of the improved design but also highlights the crucial role of simulation analysis in enhancing the safety and efficiency of rope clamps.
