Description
Данное устройство может служить и дл приема крутильных колебаний, возбужденных в стержневых образцах.This device can also serve to receive torsional vibrations excited in rod samples.
Така конструкци при ее простоте обеспечивает надежное возбуждение и прием крутильных колебаний как неподвижных, .так и движущихс образцов в ходе технологического процесса.Such a design, with its simplicity, provides reliable excitation and reception of torsional vibrations as motionless, as well as moving samples during the technological process.
Возможность взаимного перемещени пьезоэлементов позвол ет исследовать образцы различных диаметров и толщин при поддержании посто нного контактного усили , например, с помощью микрометрической головки . Повыщенна чувствительность и рабоча частота пьсзокерамическнх элементов обеспечивает возможность исследовани , например , динамического модул сдвига полимерных ориентированных образцов, отличающихс низкой сдвиговой жесткостью и большим затуханием ультразвука.The possibility of reciprocal movement of the piezoelectric elements makes it possible to study samples of various diameters and thicknesses while maintaining a constant contact force, for example, using a micrometer head. The increased sensitivity and operating frequency of the piezoceramic elements provides the possibility of examining, for example, the dynamic shear modulus of polymer oriented samples, characterized by low shear stiffness and high ultrasound attenuation.
Предмет изобретени Subject invention
Устройство дл возбуждени и приема крутильных колебаний в стержневых образцах, например, в полимерных нит х, содержащее колебательную систему с токоподводом, размещенную в корпусе, снабженном демпфирующей прокладкой, отличающеес том, что, с целью обеспечени возможности возбуждени и приема крутильных колебаний в движущихс образцах, колебательна система выполнена в виде двух идентичных плоскихA device for exciting and receiving torsional vibrations in core samples, for example, in polymer filaments, comprising an oscillating system with a current lead placed in a housing equipped with a damping gasket, characterized in that, in order to enable excitation and reception of torsional vibrations in moving samples, the oscillatory system is made in the form of two identical flat
пьезоэлемеитов, например, продольных колебаний , рабочие поверхности которых параллельны между собой и расположены одна против другой на рассто нии, равном диаметру исследуемого образца.piezoelemites, for example, longitudinal vibrations, the working surfaces of which are parallel to each other and located one against the other at a distance equal to the diameter of the sample under study.
