    • Drop test apparatus, for performing a drop impact test by dropping an article to be tested on a landing surface in a free fall state and by colliding the article with the landing surface, is equipped with a holder for holding the article and an acceleration means for accelerating the holder. The holder with the article is accelerated in the dropping direction of the article by the acceleration means, and the article is released from the holder at the point when the holder is accelerated to a predetermined speed and is dropped to the landing surface. The reproducibility of the test can be enhanced due to an elimination of an unstable factor such as frictional resistance when the holder is dropped, and a higher test in a dropping height without scaling-up the apparatus can be achieved.
    • 用于通过在自由落体状态下将待测试物品落在着陆面上并通过将物品与着陆面相撞而进行落下冲击试验的落下试验装置配备有用于保持物品的保持件和用于 加速持有人。 具有物品的支架通过加速装置沿着物品的下落方向加速,并且在保持器被加速到预定速度并且下落到着陆面的点处将物品从保持器释放。 可以通过消除诸如保持器落下时的摩擦阻力的不稳定因素,并且可以实现更高的测试,而不会使装置放大,从而可以提高测试的再现性。
