| Abstract: | Use finite element analysis of Sofidworks simulation software to build finite element models for irside and outside hexagon joints of screw pile machine＇s drill pipe. Take strength and fatigue analysis according to statics analysis and basing on two kinds of working conditions of two joints. Put forward technology which replaces quenching and tempering with forged-immediate quenching.Improve the strength of the parts, and save the cost of materials. |
