Description
В приборах, работающих на принципе крутильных весов, всегда в той или ииой мере наблюдаютс , помимо основных крутильных колебаний, кароткопериодичеокие паразитные колебани системы. Эти колебани иногда ие за тухают после за1тухагаи основных колебаний и преп тствуют точному определению положени раБновеси крутильных весов-. С подобным влением в частности столкнулись при конструированиигравитационных вариометров типа S-20, причем дл уничтожени паразитных колебаний IB этом приборе был применен спепиальный бифил рный по|Двес. Однако введение бифил ра конструктивно осложнило прибор и осложнило работу с ним, так как в полевых услови х бифил р иередко служит причиной неточносТ и наблюдений и простоев ттрибора в св зи с йровессм бифид рных нитей « т. д. Кроме тог-о, введение бифил ра- не вл етс целесообразным , а иногда и вйзмож«ЫМ дл приборов другой коНструкЦИИ; .In devices operating on the principle of torsional weights, always to some extent, in addition to the main torsional oscillations, there are always cardi-periodic parasitic oscillations of the system. These oscillations sometimes do not go out after zatuhagagi and basic oscillations and interfere with a precise determination of the position of the balance of torsional weights-. In particular, such a phenomenon was encountered in the design of gravity variometers of the S-20 type; moreover, special equipment was used to eliminate parasitic oscillations IB in this device according to | Dyes. However, the introduction of a bifil constructively complicated the device and complicated work with it, since in field conditions the bifil often causes inaccuracy of T and the observations and downtime of the tribor in connection with the bifidary filaments, etc. In addition, it is expedient, and sometimes also possible, for instruments of other instructions; .
Предлагаемый ав)Торам способ уничтоже и па.разитных короткопериодйческих колебаний применим дл любых крутилкных систем, не требует введени бифил рного подвеса и Hfe создает затруднений при полевой работе с прибором.The proposed AB) Torah method of eliminating and parasitic short-period oscillations is applicable to any torsion systems, does not require the introduction of bifilary suspension, and Hfe creates difficulties in field work with the device.
Этот способ СБРОДИТСЯ к следующему .This method WAYS TO the following.
Теоретический расчет и опытные данные показывают, что паразитные кораткопериодич)еские колебайи Представл ют сложное ма тйиковое колебание системы от1носительно верхней и нижней точек приКрепл;ени нити.Theoretical calculation and experimental data show that parasitic short-period oscillations represent a complex matic oscillation of the system relative to the upper and lower points of attachment of the thread.
Если под вли нием какого-либо случайного импульса система приобретает колебание относительно верхе1ей точки подвеса нити, то эти колебани вызывают также колебани Относи1тельно точки прик реплени нити к корамыслу. Таким образом, крутильна система эк вивалентна двум св занным коле батель«ым комплексам , собствениьге периоды колебани которых будут TI и То.If, under the influence of any random impulse, the system acquires an oscillation relative to the upper point of the thread suspension, then these oscillations also cause fluctuations in the relative point of attachment of the thread to the frame. Thus, the torsional system is equivalent to two coupled oscillators with their own complexes, whose own oscillations will be TI and T0.
Минимум устойчивости и максимум затухании этих колебаний очевидно обеспечиваетс при условии:The minimum of stability and the maximum attenuation of these oscillations are obviously provided on condition that:
