| Abstract: | Electric-pneumatic blend brake is a new brake technology.Because of relatively complex working situation and required conditions,a relay device is required to transform and record the changeable pressure signal into an electric simulation signal which is easily to be transferred and controlled.This paper mainly studies and designs a pressure difference conversion device,which can accurately use air brake power signal to control brake power magnitude at the time of electric-pneumatic blend for electric locom... |
