Welding Butterfly Valve Structural Analysis And Parameterized Design

The parameterized design is a whole process from the analyses of function to the creation of parameterized models. Parametric design, as an entirely new method of design, has been introduced abroad by industry. Such characteristics as the efficiency, practicabilities etc. that it has made it the direction of future design. It determines design efficiency and the height of designing quality and power of enterprise's key competitiveness of enterprise directly to design the level of the application level in parameter. The most of butterfly valve products are approved product, those products are well serialize, generalized, standardize and provide the proof of parametric design.This thesis has set up three-dimensional parameterized system, this system adopts Pro/Engineer, ANSYS and VC++ as tool, performs second development based on Pro/Engineer with the dynamic linking library mode. The user can input basic parameters through the man-machine interactive system, proceed the necessary check analysis and get the major parameters such as the thickness of disc, the diameter of valve stem, etc. The parameters will transmit to Pro/Toolkit application program, through the function of Pro/Toolkit transmit the models that had established by Pro/Engineer and input some auxiliary parameters. The user will get the butterfly valve three-dimensional part model and the assembled model. He also can get the schedule drawing that matchs GB and QB and contains title block.The system has set up the independent data storage system, there are standard serialization butterfly valve products'data, the user can also modify the data if he has another needs and save the data as a text file. If the user needs to use this file again, he can select this file directly.The achievement of this system has great significance. It would develop the generating efficiency of butterfly valve goods, shorten the develop cycle, improve design quality, and would also be optimize design the products through the CAE software such as ANSYS. So it is satisfy the development of modern technology.
