Valve Three-dimensional Parametric Modeling And Simulation Analysis

This article discuss about the testing simulation system of valve. Through the computer technology, it can simulate the actual working condition to test capability of valve. From the analysis result, users can mend the bug and optimize the design .The system use Ansys Workbench as the modeling and analysis platform. According to the modeling characteristic in the software, set up valve assemble modeling, and make new valve modeling via dimension parameter of valve. In the process, users can check-up the new modeling weather or not accord with actual valve product. At the end, the system can come into being mechanics result, such as stress, contact pressure, deformation and so on, and offer analysis report to users.How to confirm constructional parameters is the emphasis and difficulty in the process of modeling, if we define the parameters of the constructional frame models which are set up for FEM analysis. The article combine two methods of constructional model (down to bottom and up to tip), and make use of parametric dimension and constructional connection among some of parts, which are applied in the course of conversion parameters between main coordinate of assemble and part coordinate of parts. In order to set up the parametric models which have logical frame and reliable molding, the article put forward the essential ideas and methods about how to define constructional parameters.The technology of virtual reality has been applied in industrial design and production comprehensively. This technology has been not only transforming the way and consider of design, but also advancing the effect of production. This article integrate the technique characteristics about virtual reality, and via imitate testing, recommend the problem about how to using the technique of virtual reality in the process of industrial design, and how to put up the imitation experiment for product. This article discuss the issue of opening stress convergence on valve, and protract the graph of opening stress convergence, and modify the calculate formulae of the most stress. In addition, the article get the effectually pressure and curve through the imitate testing.
