Изобретение относитс  к испытательной технике и может быть предназначено дл  резонансных виброиспытаний изделий.The invention relates to a testing technique and may be intended for resonant vibration tests of products.

Известно устройство дл  резонансных виброиспытаний изделий, содержащее задающий генератор с элементом регулировки частоты, последовательно соединенные усилитель мощности и возбудитель колебаний, вибродатчик, устанавливаемый на испытуемом изделии, выход которого через коммутатор подключен к входу фазового детектора, второй вход которого подключен к вы-ходу задающего генератора Cl. jsA device for resonant vibration tests of products, comprising a master oscillator with a frequency control element, a power amplifier connected in series and a vibration exciter, a vibration sensor mounted on the test product, the output of which through a switch is connected to the input of the phase detector, the second input of which is connected to the output of the master oscillator. Cl. js

Недостатком этого устройства  вл етс  возможность ложных срабатываний при возбуждении изгибных колебаний , при которых колебани  про- 20 исход т не на требуемой резонансной частоте, а на смежной.A disadvantage of this device is the possibility of false alarms when bending vibrations are excited, in which the oscillations occur not at the desired resonant frequency, but at an adjacent one.
