箱型箱装配焊接过程中的扭转判据及其应用

THE CRITERION OF TWISTING FOR BOX GIRDER IN ASSEMBLING WELDING PROCESS AND IT'S APPLICATION

建立了装配焊接过程箱型梁的扭转判据.并应用判据阐明箱型梁扭转变形的基本性质,建立箱型梁扭转矫正量计算的通用方法.

In this paper, the criterion of twisting deformation is established for box girder in assembling welding process, and the nature of twist is clarified with this criterion. In addition, a general method of calculating the corrective value of twisting deformation is set up.
