| Abstract: | On the basis of rail wear successive measurement in the typical sharp curves of Shanghai metro lines,the side wear and vertical wear of rails and their growth rate are analyzed.The data shows that rails on the sharp curve are affected by the side wear,vertical wear and irregular wear altogether.The average growth rates of side wear and vertical wear are about 0.019 mm/d and 0.005 mm/d respectively in long-formation and heavy-train line.While in short-formation and light-train line,the two indexes are about ... |
