The paper studies on relations between railway rolling stock and peripheral interfaces in Japanese railways.It covers the relations between wheel and rail,the relations between pantograph and catenary,the air dynamics,track circuit and noise,etc.In the study on relations between wheel and rail,the adhesive property between wheel and rail,the lubrication of wheel and rail and wear reduction between wteel flange and inner rail corner were analyzed.In the study on relations between pantograph and catenary,the author focused on the contact status between the pantograph and catenary,e.g.,how to minimize the variation of the contact force,causes of the variation and the protection measures.In dynamics study,Increase of rolling stock shock in tunnels and shock absorption measures are analyzed.In track circuit study,reduction of wheel/rail contact resistance is analyzed.In noise study,causes of rolling noise and structural noise as well as the numerical value module are analyzed. 展开更多
