摘要： There is provided a drop tester for a filled sack, comprising a substantially vertical linear drive unit having a sleigh movable in the direction of the extension of the linear drive unit, a platform for receiving the filled sack attached to the sleigh such that the platform may be moved in a substantially vertical direction, a fundament arranged under the platform such that the platform may be positioned on or just above the fundament, and a motor system connected to the sleigh, said motor system being capable of accelerating the platform above 1 g downwards. There is also provided method of drop-testing a filled sack, comprising the steps of: providing the sack on a platform in an upper position; accelerating the platform downwards above 1 g such that the sack is allowed to fall freely from the upper position; and stopping the platform in a lower position on or just above a fundament such that the falling sack hits the platform in the lower position and the impact of the hit is absorbed by the fundament.
摘要翻译：提供一种用于填充袋的跌落测试器，其包括基本上垂直的线性驱动单元，该线性驱动单元具有可在线性驱动单元的延伸方向上移动的滑块，用于接收附接到滑块的填充袋的平台，使得平台可以在基本上垂直的方向上移动，布置在平台下方的基础使得平台可以定位在基础上或正好在基础上方，以及连接到雪橇的马达系统，所述马达系统能够使平台加速超过1克向下。还提供了对装满的袋子进行跌落测试的方法，包括以下步骤：将袋子提供在处于上部位置的平台上; 将平台向下加速至1g以上，使得袋子可以从上部位置自由落下; 并将平台停止在基础上方或正好在基础上方的较低位置，使得落下的袋子在较低位置撞击平台并且击打的影响被基础吸收。
