Abstract
1. Способ исследования демпфирующих свойств материалов, заключающийся в том, что образец исследуемого материала нагружают циклами затухающих колебаний механической нагрузки, а в повторных циклах меняют уровни нагрузок, отличающийся тем, что затухающие колебания в цикле поочередно прикладывают с разных концов образца, а в повторных циклах меняют уровни и соотношение нагрузок на разных концах образца. ! 2. Устройство для исследования демпфирующих свойств материалов, содержащее основание, установленные на нем неподвижный и два подвижных захвата образца, ось вращения, штангу, установленную на оси вращения, груз, закрепленный на штанге, приспособление для соединения штанги с подвижными захватами, отличающийся тем, что приспособление для соединения штанги с подвижными захватами выполнено в виде коромысла, установленного на оси штанги и жестко с ней соединенного, подвижные захваты закреплены на разных концах коромысла, а неподвижный захват закреплен на оси штанги, при этом ось штанги выполнена с возможностью поворота относительно основания, между осью и основанием размещен фиксатор поворота оси штанги, при этом штанга выполнена упругой. 1. A method for studying the damping properties of materials, which consists in the fact that the sample of the studied material is loaded with cycles of damped oscillations of the mechanical load, and in repeated cycles the load levels are changed, characterized in that the damped oscillations in the cycle are applied alternately from different ends of the sample, and in repeated cycles change the levels and the ratio of loads at different ends of the sample. ! 2. A device for studying the damping properties of materials, comprising a base, a fixed one and two movable sample grips mounted on it, an axis of rotation, a rod mounted on the axis of rotation, a load fixed on the rod, a device for connecting the rod with movable grippers, characterized in that the device for connecting the rod with movable grippers is made in the form of a beam mounted on the axis of the rod and rigidly connected to it, movable grippers are fixed at different ends of the beam, and the stationary gripper fixed on the axis of the rod, while the axis of the rod is made to rotate relative to the base, between the axis and the base there is a latch for turning the axis of the rod, while the rod is made elastic.
