Abstract This paper focuses on the structural failures of various high-speed trains in China. The reasons for the structural failures of the trains are analyzed based on their design and service condition. Based on examples considered in the present paper, an optimization design method and a reasonable structure are put forward. For the motor car of the high speed train “Blue Arrow” dynamic stresses in service are investigated through field tests and theory analysis. According to the dynamic stress obtained by measurement on site, some results to evaluate service life are obtained.
