Study of Multiple Environmental Stress Accelerated Test Method for Electronic Brake Control Unit
Electronic Brake control unit is key component of the brake system for railway vehicles,used for the processing brake control signals,its stability and reliability are directly related to the normal and efficient operation of the brake control system for railway vehicles.In order to meet the designed life requirements of 30 years for the CRH train and evaluate product life under complicated working environment,it is necessary to analyze the structure,operation condition and failure mechanisms,stimulate the potential failure mode of electronic brake control unit through accelerated life test,and conduct life analysis of the failure mode.Through the research on the cyclic multiple environmental stress accelerated test method of the electronic brake control unit,an effective replace is realized to the life evaluation of the available electronic brake control unit.
