Description

В известных гравиметрах дл  измерени  силы т жести земли примен ют кварцевые ма тники. Однако они ие нозвол ют производить измерени  нри движении объекта, на котором установлен ирибор.In known gravimeters, quartz models are used to measure the earth's gravity. However, they are not allowed to measure when the object on which the device is installed is moving.

Предлагаемое устройство позвол ет вести измерени  при двин-сении объекта (например, корабл , подводной лодки и т. д.), а также увеличить точность измерени . Это достигаетс  тем, что в нем применен трехстепенный гироскоп, центр т жести которого смеиден относительно оси п0двеса.The proposed device allows measurements when the object is moving (e.g. ships, submarine, etc.), as well as increasing the measurement accuracy. This is achieved by the fact that a three-degree gyroscope is used in it, whose center of gravity is adjacent to the axis of the suspension.

На чертеже показано схематически устройство дл  измерени  силы т жести. The drawing shows schematically a device for measuring gravity.

Центр т жести гироскопа смещен на рассто ние / от точки оиоры. Под действием ускорени  силы т жести такой гироскоп, помещенный Е кардаиовый подвес с трем  степен ми свободы, начнет прецессировать вокруг направлени  силы т жести. Углова  скорость оз,., этой прецессии будет пропорциональна ускорению силы т жести g. где; соо-скорость вращеии  ротора гироскоиа;The center of gravity of the gyroscope is shifted to / from the point of oiors. Under the action of the acceleration of the force of gravity, such a gyroscope, an E-suspended carda with three degrees of freedom, will begin to precess around the direction of gravity. The angular velocity oz,., Of this precession will be proportional to the acceleration of the force of gravity g. Where; the co-rotational speed of the gyroscopic rotor;

А - момент инерции ротора относительно главной оси; от - масса ротора гироскопа;And - the moment of inertia of the rotor relative to the main axis; from - the mass of the gyro rotor;

/ - рассто ние от точки оиоры до центра т жести ротора. Отсюда получаем:/ is the distance from the oiory point to the center of gravity of the rotor. From here we get:

Зна  значени  правой части уравнени , можно нолучить ускорение силы т жести.If you know the value of the right side of the equation, you can get an acceleration of gravity.

Л -т;,- («о  L-t;, - ("o

Во избежание вли ний изменени  плотности воздуха на момент гироскопа, необхходимо ввести барометрическую компенсацию, установив на оси ротора гироскопа полый герметически закрытый сосуд.In order to avoid the influence of the change in air density at the time of the gyroscope, it is necessary to introduce barometric compensation by installing a hollow hermetically sealed vessel on the axis of the gyroscope's rotor.

Предмет изобретени Subject invention

Устройство дл  измереии  силы т жести, отличагоЩеес  тем, что, с целью повышени  точности измерени  и дл  возможности вести наблюдени  во врем  движени  объекта, в нем применен трехстепенный гироскоп, центр т жести которого смещен относительно оси подвеса .A device for measuring gravity, characterized by the fact that, in order to improve measurement accuracy and to be able to observe during the movement of an object, it uses a three-degree gyroscope whose center of gravity is shifted relative to the axis of suspension.
