碩士 === 明新科技大學 === 精密機電工程研究所 === 102 === Based on the speedy development of CAE software, the mechanical analysis engineers can get the related data of the design such as stress, strain, movement, deformation through CAE simulation. But, how to implement the tool more efficient on the facing issues is also a challenge to engineers. Thus, this paper proposes a set of procedure to make sure the validity of the products before the products are on sale. The main objective of these papers is to applying Taguchi method to find out optimal setting of parameters for phone case CAD model design and rapid prototyping during using the techniques of reverse engineering. The research has three parts. The first, picking up five phone case which are on sale to analyze, using 3D plotting program “Pro/E” to design the model’s sample and size. The second, transforming of the mode to the finite element program “ANSYS”, and dividing the element. Use “ANSYS” to analyze the stress and displacement of the model structure, and evaluating the model’s feasibility and deciding the new model size. The third part is to figure out the model’s best way and sensitivity. The third part is to figure out the model’s best way and sensitivity. Find the best value through Taguchi Method. We find out the result can satisfy the demand and the cost that we expect. We hope the phone case that we design can improve some defects of phone case which are designed recently and enhance our products competitive in the market.
