由於國際鋼鐵價格飆漲,鋼鐵製的相關產品製造成本提高且回收價值可觀,因此引起不少不法人士的覬覦,一般道路上常使用的鑄鐵水溝蓋便成為偷竊的目標。為了降低失竊率,本文將原本鑄鐵材質的水溝蓋改為纖維加強高分子複合材料的水溝蓋,並針對水溝蓋的不同造型加以分析。
理論分析將分為三部份進行,第一部份運用Pro/Engineer 3D繪圖軟體建立水溝蓋的模式及相關的尺寸。第二部份為根據所建立之水溝蓋模型轉換到有限元素分析軟體ANSYS上,並進行模型元素的網格化及邊界條件的建立,之後再以ANSYS求得水溝蓋應力及變形的狀況。第三部份為使用田口式最佳化設計軟體,求出水溝蓋模型的最佳化設計尺寸,達到在設計水溝蓋上安全、經濟的目的。
Owing to the rise of the international steel price, the cost of the related steel product raises and the recycle price is considerable. Therefore, the drain ditch covers made by cast iron become the target of the thefts. In order to reduce rate of stealing, this thesis proposes Fiber Reinforced Plastics (FRP) to replace original material of the cast iron of the drain ditch covers. In this study, different types of the drain ditch covers will be analyzed.
The theoretical analysis procedure is divided into three parts. The first part is to use the 3D graphic software Pro/Engineer to build the drain ditch cover model and its related size. The second part is to base on the designed model and transfer the model to the finite element program “ANSYS” and build the model element mesh. After that, by setting up the boundary and loading conditions, the stress and deformation of the model structure are determined by ANSYS. The third part is to use the “Taguchi Method” to optimize the size of the drain ditch cover model. It is expected to design an optimal drain ditch cover which is safe and economic.
