摘要

铝合金型材的高精度拉弯是汽车车架制造的关键技术。采用有限元分析软件对高速铁路用典型L型铝合金型材的位移控制过程进行了数值模拟研究。研究了不同摩擦系数、有无挡板和盖板对等效应力、应变和截面畸变的影响。结果表明，摩擦系数的增加会增加截面畸变、等效应力和应变。挡板和盖板的安装可以显著减少型材中间截面的畸变，并在一定程度上增加等效应力和应变。

Numerical Simulation of Stretch Bending for L-section Aluminum Alloy Profile

High precision stretch bending of aluminum alloy profile is the key technology for making car’s frame body. A numerical simulation study on the displacement-controlled process for a typical kind of L-section aluminum alloy profile used in high-speed rail with finite element analysis software is presented. The effect of different friction coefficients, with or without baffle and cover plate on the equivalent stress,strain and cross-sectional distortion are investigated. It is shown that the increase of the friction coefficient can increase the cross-sectional distortion, equivalent stress and strain. The installation of baffle and cover plate can significantly reduce the cross-sectional distortion in the middle section of the profile, and increase the equivalent stress and strain to some extent.

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
