摘要： The supporting apparatus is disposed between a fixed portion and a moving portion facing the fixed portion at a predetermined distance, and supports the moving portion which vibrates while maintaining parallelism to the fixed portion. The moving portion and the fixed portion are respectively provided with receiving members 2F, 2M facing each other. The receiving members 2F, 2M sandwich, under pressure, a rocking member 4 which limits a movement of the moving portion in crosswise directions Y vertical to vibrating directions R of the moving portion while rocking about Its axis accompanying the vibration of the moving portion in the vibrating directions (R).

摘要： 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.
