本文較系統地總結了鋼軌接頭的構造、形式、功能,並對接頭區的缺陷及接頭病害作了簡單的介紹。Commonly, if slide between joint bar and rail is permitted, the bolt torque ranged from 500n - m to 700n - m is suitable. if the joint is " frozen ", the bolt torque should range from 900n - m to 1100n - m
一般來說,如果允許夾板與鋼軌相互滑動,接頭扭矩500 700n ? m范圍是適宜的;如果將接頭「凍結」 ,則螺栓扭矩應在900 1000n ? m左右。As the analysis shows that stress of the outside joint bar of rail is higher than that of the inner joint bar when a wheel rolls over the rail joint. furthermore the change of bolt tension has great effect to the stress distribution and stress level of all parts of rail joint
分析表明:接頭受力時,鋼軌外側夾板的應力水平比內側夾板的應力水平高;在受力條件相同的情況下,螺栓扭矩的變化對接頭各部件的應力分佈及應力水平有較大影響。分享友人
