摘要
Abstract
In order to explore the influence law of springback in bend forming process and improve the processing accuracy,taking 6061-T6 aluminum alloy pipe as an example,conducts simulation experiments by ABAQUS finite element software,and explores the influence of material parameters of elastic modulus,Poisson's ratio,pipe wall thickness and process parameters of feeding speed and friction coefficient on pipe bending and springback.The results show that Poisson ratio has the smallest effect on the springback angle of the tube bending,while wall tube thickness has the largest effect.The increase of friction coefficient will make the springbackangle increase first and then decrease,and the effect of feeding speed is less than that of friction coefficient.关键词
