大型厚板曲面件的多点成形仿真
Simulation on flexible multi-point forming of large-scale thick-plate curved parts
摘要
Abstract
Traditional manufacturing methods of thick-plate curved surface parts have problems,such as high cost and low efficiency,and the multi-point forming technology provides a solution.In the multi-point forming technology,it is difficult to determine the process parameters because of spring-back,which increases the number of experimental operations and reduces the forming efficiency.In or-der to improve the forming efficiency,the simulation through ABAQUS,one finite element software,was combined with experiments to study and analyze the sheet metal forming in this paper.Firstly,three-dimensional modeling and simulation of the sheet-forming process was carried out using finite ele-ment software.Then compensation modification of the mold curved surface was carried out by analyz-ing the simulation results.Finally,experiments were performed on the modified mold curved surface to obtain the parts that meet the requirements.The forming experiments on the modified mold surface can reduce the number of operations and improve the forming efficiency,which provides a reference for subsequent research.关键词
