碩士 === 大葉大學 === 工業工程與管理學系 === 103 === The development of composite materials has been quite mature having excellent material properties for past decade. However, the traditional metal materials can’t avoid to be replaced by using composite materials. Composite materials have been different rigidity and strength owing to the angle of stack. In past, traditional stacking sequence was used by trial and error, therefore, the structures will waste unnecessary materials and also increase the structural weight. The aim of the study is to develop a composite structural optimization module with automatic calculate functions. The layerup optimization module was developed by finite element method (FEM) combined with genetic algorithm framework in ANSYS environment. ANSYS APDL language was adopted to develop a discontinuous optimal simulation of composites damage prediction module. The system calculates the forecast simulation process parameters included laminated angle, laminate thickness, and different type of material properties, then summarized trends and predict the behavior of possible structural damage as a reference data to lightweight structure. In this paper, the optimal accuracy and feasibility analysis module damage will be verified between computer simulation and actual products. Based on the study, the composite structural parameters can be applied to relative industrial, reduce the weight of the structure module, speed up the developing time ,and finally cost down the develop expense.
