Abstract
Изобретение относитс к испытательной те.чнике и может быть использовано дл определени характеристик усталостной прочности материалов. Целью изобретени вл етс повьииение точности путем учета де.мпфирующих свойств материала и снижени износа контактирующих элементов. На станине 1 с за.хватами 2 дл консольного креплени образцов 3 установлен вал 4, а на нем барабан 5 с роликами 6. При вращении барабана образец 3 отклон етс посредством ролика 6 }ia заданный ирогиб, а затем сойер1нает свободные колебани до следующего нагружени . 1 ил.The invention relates to a test book and can be used to determine the fatigue properties of materials. The aim of the invention is to improve the accuracy by taking into account the damping properties of the material and reducing the wear of the contacting elements. Shaft 4 is mounted on frame 1 with latches 2 for cantilever mounting of samples 3, and drum 5 with rollers 6 is mounted on it. When the drum rotates, sample 3 is deflected by roller 6} ia given irogib, and then it saves free oscillations until next loading. 1 il.
