Description
В известных фильтрах крутильных колебаний, в св зках которых происход т продольные колебани , наименьша длина резонаторов получаетс равной половине длины волны. Дл частот, например, пор дка 50 кгц фильтры с полуволновыми резонаторами слишком громоздки, резонатор из стали имеет длину 25 мм.In the known torsional vibration filters, in the bonds of which longitudinal oscillations occur, the shortest resonator length is equal to half the wavelength. For frequencies, for example, about 50 kHz, filters with half-wave resonators are too bulky, the resonator made of steel has a length of 25 mm.
Предлагаемый фильтр позвол ет уменьшить габариты, расширит полосу пропускани и устранить паразитные полосы пропускани вблизи основной. Это достигаетс применением крутильных резонаторов гантельной формы, у которых св зки соединены с резонаторами в местах изменени понеречного сечени резонаторов.The proposed filter allows to reduce the size, widen the bandwidth and eliminate spurious bandwidths near the main band. This is achieved by using dumbbell-shaped torsional resonators, in which the bindings are connected to the resonators in places where the cross-section of the resonators changes.
Конструкци фильтра показана на чертеже. Расчетами, а также экспериментально доказано, что такое соединение св зок с резонаторами обеспечивает лучшие электрические характеристики фильтров. Отсутствие наразитных колебаний обусловлено как формой резонаторов, так и соединением их в точках скачкообразного измеиенн сечени .The filter design is shown in the drawing. Calculations, as well as experimentally proved that such a connection links with the resonators provides the best electrical characteristics of filters. The absence of parasitic oscillations is due both to the shape of the resonators and to their connection at the points of the jump-like measuring section.
Предмет изобретени Subject invention
Электромеханический полосовой фильтр с механическими резонаторами гантельной формы, в которых возбуждаютс крутильные колебани , соединенными между собой посредством проволочных св зок, отличающийс тем, что, с целью расширени полосы проиуска 1и и. устрапени паразитных полос пронускани вблизи основной, соединение св зок с резонаторами осуществл етс в местах изменени поперечного сечении резонаторов.An electromechanical band-pass filter with dumbbell-shaped mechanical resonators, in which torsional vibrations are excited, interconnected by means of wire ties, characterized in that, in order to broaden the production band, 1 and. arranging parasitic penetration bands near the main one; the links to the resonators are connected at the places where the cross section of the resonators changes.
