| Abstract: | In an attempt to determine the distribution of natural frequency, frequency-scanning tests are conducted in the outside doors and inside doors of high-speed trains by adopting electro-motion vibration test system. This paper also analyzes the likely causes responsible for the differences between outside door natural frequency and inside door natural frequency, proposing that natural frequency and subsystem or parts of inside door system should be connected. Scanning frequency excitation is an efficient way in which the distribution of natural frequency of high-speed train doors can be determined, which can be used to improve the vibration quality of high-speed train door system. |
