Формула изобретени  Вибратор бигармонический дл  динамических изделий, например, весоизмерительных приборов и стендов, содержащий платформу с дебалансами и низкочастотный фильтр, о тличающийс  тем, что, с целью увеличени  точности поддержани  среднего значени  параметров низкочастотных колебаний и их регулируемого усилени , низкочастотный фильтр выполнен в виде разрезного стакана, св занного т гой с вибратором, и поршн , имеющего возможность перемещени  в стакане и св занного т гой испытуемым изделием, причем между дном стакана и поршнем установлена пружина сжати , а на внешней поверхности стакана установлены регулирующа  гайка, пружина сжати  и коническое кольцо, упирающеес  в конические выступы.(54) VIBRATOR BIGARMONIC rotate in pairs and oppositely with equal angular speeds, each pair of unbalances 2 creating oscillations directed to opposite sides with frequencies he and C02, which are transmitted to 10. 10. A low-pass filter formed by masses of split cup 13 and platform 1 with vibrators , as a result of the stiffness of the spring 14 and the friction between the surfaces of the split cup 13 and the piston 15, caused by the pressure of the spring 19 through the ring 18 on the conical rim of the split cup 13, does not let the object under test oscillations with frequencies P1 p (02 p transmits only low-frequency oscillations whose frequency is equal to the difference between the frequencies coi and co). In this case, the amplitude of the oscillations is controlled by selecting the spring stiffness 14 and changing the spring tension 19, i.e. the low-pass filter is simultaneously adjustable resonant amplifier of low-frequency oscillations. Increasing the accuracy of the average value of the parameters of low-frequency oscillations is achieved due to the fact that, on their own weight, the components and parts of the vibrator are suspended from the object under test through a low-pass filter. The invention is a biharmonic vibrator for dynamic products, for example, weighing instruments and stands, containing a platform with unbalances and a low-pass filter, characterized in that, in order to increase the accuracy of maintaining the average value of the low-frequency oscillations parameters and their adjustable amplification, the low-pass filter is made a cup connected with the vibrator and a piston having the ability to move in the glass and connected with the test article being hard, and between the bottom of the glass and the A compression spring is installed, and an adjusting nut, a compression spring, and a tapered ring resting on the conical protrusions are installed on the outer surface of the glass. tpvi.2tpvi.2
