Cracking analysis and structural optimization of lifting drum in dry quenching
LIU Quan
Abstract：A finite element model was presented to investigate cracking phenomenon of the lifting drum in dry quenching in Meigang,according to characteristics of the drum structure and cracking.Stress and deformation of the lifting drum were simulated.An optimization design of the lifting drum was made.Then,once again,a new finite element model was built,and stress and deformation were simulated as well.Through comparing stresses,strain and short stress line before and after optimization,there was more small deformation and short stress line lengthens obviously to new lifting drum.Using of optimized lifting drum provided a reasonable techni-cal support for avoid cracking and deformation failure.
