Research And Implementation Of Interactive CAD Of Structure Of 3-D Woven Composites

Computer Aided Design is that in order to help designer complete design of engineering, people set a special environment and use program complete computational work instead of hands by using powerful capability of data processing of computer. As a result, Computer Aided Design can improve automation of design, save labor, shorten periods of design and enhance work efficiency.Process of design is tending towards semi-automation and automation by using Computer Aided Design system. Computer Aided Design liberate designer from cockamamie, bald and repetitious computing and drawing word, and make them can do more innovative work.perfect computer design(no computer aided design) ought to do some work as follows, computer auto-design structure and technologic parameter of woven and output perfect structure and parameter according to demand of mechanical capability of woven composites in engineering. There are distance between computer aided design and this target.Designer designs structure of woven composites according as requirement of him in the interactive CAD system. The interactive CAD system has excellent function, such as withdraw, comeback and change the color of warp. Designer chooses material, configure structure of fiber and pre-configure technologic parameter. CAD software use EPS software and quickly simulate elastic properties, and save result of simulation as a case in backup database. All of result of simulation will save in backup database. Computer simulate expert to judge result of simulation and choose a optimum structure.CAD of Three-Dimensional woven composites will provide theoretical gist for actual work in choosing structure of woven composites and technologic parameter-choose material, configure structure of fiber and pre-configure technologic parameter. This can guide designer of woven composites to design woven composites, and design high-powered material in lower cost.
