本文针对这一现状开发了一个专门针对焊接过程数值模拟的有限元前处理系统,并应用该系统建立了某型号导弹油箱结构的焊接有限元模型,分析了该结构的焊后变形规律。 - As an application of this fem preprocessing system , the simulation on the welding process of missile ’ s oil box was performed , in which the effects of the welding sequences of four web plates and welds on each web plate are primarily analyzed . the simulation results show that the deformations under varied welding sequences are almost the same . downward deflection deformation is obtained along the weld longitudinal direction in the structure as well as upward deflection deformation along the weld traverse direction
对于某型号导弹油箱结构焊接过程的数值模拟计算,主要考察了每块立板上各段焊缝焊接顺序的调整、四块立板之间不同的焊接顺序以及焊接起始端的选择对结构焊后变形的影响规律,模拟结果表明:壁板在各种焊接顺序下的整体变形规律基本相似,即焊后壁板沿焊缝纵向发生了向下的挠曲变形,中部向下变形量最大;沿焊缝横向发生了向上的挠曲变形,壁板两端部变形量较大,且壁板前端变形大于壁板后端。
