Abstract

Изобретение относитс к испытани м материалов. Целью изобретени вл етс расширение функциональных возможностей за счет создани как одиночного импульса раст жени , так и ступенчато возрастающей раст гивающей нагрузки. Установка содержит платформу 2 с приводом 3 вращени , два груза 4 и 5 с фиксаторами 6 и 7, направл ющую 8 дл грузов, захваты 9 и 10 дл образца 11. Захват 10 соединен с т гой 12, установленной вдоль направл ющей. Фиксаторы обеспечивают соединение грузов с т гой. Смещение грузов вдоль т ги определ етс ограничителем взаимного перемещени грузов, включающим закрепленную на грузе 4 и свободно проход щую через груз 5 штангу 16 с упором на ее свободном конце. Под действием центробежных сил грузы последовательно перемещаютс вдоль т ги, обуславлива ступенчатое нагружение образца. 2 ил.This invention relates to material testing. The aim of the invention is to enhance the functionality by creating both a single stretching pulse and a stepwise increasing tensile load. The installation comprises a platform 2 with a 3 rotation drive, two weights 4 and 5 with clamps 6 and 7, a guide 8 for weights, grips 9 and 10 for sample 11. The hook 10 is connected to a pull 12 installed along the guide. Clamps provide connection of goods with a thy. The displacement of loads along the pull rod is determined by the limiter of mutual movement of loads, which includes a rod 16 fixed on the load 4 and freely passing through the load 5 with an emphasis on its free end. Under the action of centrifugal forces, the weights are successively moved along the rod, causing the sample to be stepped. 2 Il.

Claims

Claim

A centrifugal installation for impact testing of materials, comprising a base, a platform mounted on it with a rotation drive, grippers for a sample, two load platforms with clamps located on one side of the axis of rotation, a load guide radially located on the platform, and a load limiter characterized in that, in order to expand the functionality by creating both a single tensile impulse and a stepwise increasing tensile load, it is equipped with a joint connected with one of the grips and installed along the guide rod, with which the loads are connected through the clamps, and the limiter for the mutual movement of goods includes a rod fixed on one of them and freely passing through the other load with an emphasis on its free end.
