Vibration test method and apparatus of vehicle parts

摘要

The present invention is to provide a method for testing vibration of automobile parts which can test resonance vibration of automobile parts having natural frequency at a frequency band deviated from a set vibration frequency range of an exciter. According to the present invention, the method for testing vibration of automobile parts performs vibration test of automobile parts and includes checking if the natural frequency of an automobile part is within the vibration frequency range of an automobile; if the natural frequency of the automobile part is not within the vibration frequency range of the automobile, adding mass to the automobile part to lead the natural frequency of the automobile part to the vibration frequency range of the automobile; and exciting the automobile part, to which the mass is added, for a set number of times in the vibration frequency range of the automobile.
