Research And Development On Sheet Forming Simulation System Based On UG NX

With the developments in the methods of finite element simulation, sheet metal forming simulation software has become more important in sheet forming. However, the existing CAE software is too specialized, demanding of users, which are independent of CAD system. In the other hand, some CAE software increase design function, but the poor accuracy of surfaces affects the accuracy of the simulation results. Therefore, development a simple, rapid, unified interface CAD and CAE seamless integration system, to Nondestructive achieve efficient finite element analysis, is of great significance.This research is supported by NSF project "The Independent Research of High-speed Simulation and Optimal Process Design aiming at the Formability of Automobile Panel" (NO.50575080) and National 863 Program project: "The Formability and Optimal Process Design Based on the Simulation of Automobile Parts"(NO. 2006AA04Z140). The Forming Analysis Wizard system (FAW) based on UG NX has been researched and developed.In this paper, UG application development environment and development tools have been introduced firstly. The framework of UG application development and the ways of function achievement have been researched. By analyzing the architecture and design mode of the existing sheet metal forming finite element software, summed up the design principles, completed the system functional requirements analysis and design of the interface. Realized of the system functions based on modular .The key technologies of development have been discussed.Forming Analysis Wizard based on UG NX is a rapid, unified interface CAD and CAE integration system. It can evaluate the stamping feasibility of part designs during product development and initial stages of tool design. FAW system use FASTAMP/Explicit solver, the interface style consistent with UG, achieve a seamless integration with the UG.FAW system based on updated dynamic explicit approach and BT shell element, considering real influence of friction, holding force and drawbead and so on.
