Parametric Design And Finite Element Analysis Of Ceiling

To use the Pro/E parametric platform to set the parametric model of the overall framework of the product structure, summarized the parametric modeling methods of parts, components, and frequently asked questions in the process of the parametric model, saved time for the smooth implementation of parametric design, it can quickly transform the designer's design intent into 3D model, then parametric modify the unreasonable formulas and sizes, the final product mix will change the overall framework for the actual needs of the product, provide a powerful means of improving the efficiency of product design, gain time to win the market share, shorten the product development cycle largely, and increase productivity. At the same time, at present the domestic ceiling's structure is single, the check of ceiling's strength often use experiential formula, the development of new products also using the same experiential formula often make greater error, unable to meet changing market demand, in the use of ANSYS structural analysis module to analysis the structural mechanics of parametric model, it is able to greatly enhance the safety and reliability of Elevator products, shorten the time of checking largely, to a great extent shorten the time of the product putting into production, save a lot of human material and financial resources. Finally, it can reduce the cost of the product. If combine CAD/CAE to achieve the automatic modeling and analysis of structural mechanics, it will be a big step forward.This topic does the research on the SUPEX trapezoid ceiling of Suzhou Jiangnan Express Elevator Company, combining the products existing BOM production system, takes full advantage of Pro/Engineer and the second development tools Pro/Program, Pro/Toolkit, Family Table. By the thinking of introducing feature based parametric modeling, pick-up the information of database using VBA language, the output BOM. Finally, in the use of ANSYS structural analysis module to analysis the strength of structural mechanics of parametric ceiling model. The parts which strength does not meet the requirements are proposed the feasible amend, afresh study out design parameters, feedback to the design parameters of the lift platform, rapid generation to meet strength requirements of the elevator products, combine CAD/CAE to achieve the automatic modeling and analysis of structural mechanics.
