| Abstract: | The flexural fatigue strength of the doub1e flash welded joint between high manganesesteel and rail steel has been investigated. The fracture sufaces have been observed by SEM. TheresultS show that the double nash we1ded joint between high manganese steel and rail steel possessesa higher flexural fatigue strength than the high manganese steel base meta1.key words: high manganese steel, rail steel; flash welding, flexural fatigueThe paramet6r Drawing Dedgn f0r the H0b Used bef0re GrindingKong Xanshu Tang Yisheng Li Lixing(Dept. of Mechanica1 Engineering)Abstract: Based on the optimized design about the profi1e of the hob used before grinding for thetraction gear, the method of parameter drawing design was used to draw the serial of the hob usedbefore grinding. The algorithm of parameter drawing design was studied to draw the draft of thehob which was to make the traction gears for high speed locomotives. It was completed fordrawing The hob used for the traction gear in "DONGFENG DF lO" and "SS8- Il ~ highspeed locomotives. |
