Description

Известные устройства дл  определени  неравножесткости упругой механической системы ло двум взаимно перпендикул рным направлени м путем измерени  периодов свободных колебаний физического ма тника , образованного контролируемой системой, имеют низкую точность измерени  из-за значительного вли ни  на результаты измерени  трени  в собственных опорах системы.The known devices for determining the unequal elasticity of a mechanical system in two mutually perpendicular directions by measuring the periods of free oscillations of a physical model formed by the system being monitored have a low measurement accuracy due to a significant effect on the results of measuring friction in the system's own supports.

Предлагаемое устройство выполнено в виде качающейс  рамы на призматических опорах с прикрепленными к ней опорными площадками. Устройство также снабжено двум  закрепл емыми на цапфах контролируемой системы квадратными втулками с плоскопараллельными гран ми , которые с помощью плоских пружин фиксируютс  на опорных площадках рамы. Указанное отличие .позволило повысить точность измерени  |Путем исключени  трени  в собственных опорах системы и вли ни  их оваоТ ьности.The proposed device is made in the form of a swinging frame on prismatic supports with supporting platforms attached thereto. The device is also equipped with two square bushes fixed to the pivot points of the controlled system with plane-parallel faces, which are fixed with the help of flat springs on the support surfaces of the frame. This difference has allowed to increase the accuracy of measurement by eliminating friction in the system’s own supports and the influence of their function.

На- чертеже изображено предлагаемое устройство.The drawing shows the proposed device.

Испытуема  упруга  механическа  система / с цапфами 2 и закрепленными на них квадратными втулками 3 устанавливаетс  на опорных площадках 4, которые жестко прикреплены к качающейс  на призматических опорах 5 рамс 6. Квадратные втулки 3 выполнены с плоскопараллельными гран ми, а их фиксаци  на опорных площадках 4 осуществл етс  с помощью плоских пружин (на чертеже не показанных).Tested elastic mechanical system / with trunnions 2 and square bushings 3 fixed on them is mounted on supporting platforms 4, which are rigidly attached to ramps 6 rocking on prismatic supports 5. Square bushings 3 are made with plane-parallel edges, and their fixation on supporting platforms 4 is carried out by means of flat springs (not shown).

Испытуема  система и подвижные части устройства представл ют собой физический ма тник, периоды колебаний которого измер ютс  при установке системы сначала на одну плоскость квадратных втулок 5, а затем на другую плоскость, перпендикул рно к первой. Разность периодов колебаний и будет величиной, пропорциональной искомой неравножесткости упругой механической системы.The system under test and the moving parts of the device are a physical model, the periods of oscillations of which are measured when the system is installed first on one plane of square bushes 5, and then on another plane, perpendicular to the first. The difference between the oscillation periods will be a value proportional to the sought unequal elasticity of the elastic mechanical system.

Предлагаемое устройство может найти широкое применение лри проведении различных экспериментальных работ дл  определени  неравножесткости упругой механической системы.The proposed device can be widely used in carrying out various experimental work to determine the inequality of an elastic mechanical system.
