Fixtures Design for Controlling Distortion of Pressure Vessel During Fabrication

The purpose of this study is to develop the integrated design system of supports, which are turning roller, dent pad and bracing pipe to control distortion of the pressure vessel. The optimum design condition for each support was established by analytical solution and finite element analysis with simple model and verified by comparing with the results of FEA for actual model. Based on the results, the Window-based computer program was developed using Visual C++. The program supports component feature-based modeling. In addition, user can easily determine the condition of supports and jigs during manufacturing of pressure vessels with user-friendly functions such as the material database of ASME, easy input, and detail output.Copyright © 2003 by ASME
