Abstract
Disclosed is a vibration test method for evaluating the vibration resistance of a specimen, comprising a test specification setting step (S10) of determining reference vibration conditions for the specimen based on transport conditions during actual transportation; a reference value attainment step (S20) of calculating an amplitude level and a reference accumulated fatigue value of the specimen under the reference vibration conditions; a test condition determination step (S30) of determining test vibration conditions and a test time based on an allowable amplification factor of the amplitude level and a desired vibration time, so that an accumulated fatigue value which is calculated from the vibration detection value of the specimen satisfies the reference accumulated fatigue value; and a vibration-imparting step (S40) of vibrating the specimen based on the test vibration conditions and the test time. In accordance with the vibration test method, a vibration test that conforms to the actual transportation environment can be readily performed with high accuracy.
