Reliability Test Design Method of Reconnected Fine Cable on EMU Train

Abstract

Reconnected program contribute to the maintenance of local aging fine cable on Electric Multiple Unit (EMU) train. But the study of reliability test for the reconnected cable has been lacked. This paper proposed a design method of tests to verify the function, environmental suitability and reliability of reconnected cables. The method was introduced from two aspects: original performance affected and new performance to be considered. Particularly, the reasonability and feasibility of method were discussed as well. Finally, the proposition of reliability test method was applied to a case of reconnected fine cable on EMU train, in which we figured out a series of test.
