| Abstract |
Background. The development of a pilot information-measuring system allowing to determine the dynamic characteristics relate to properties of the object of study.
Results. Developed experimental and measurement system allowing to determine the dynamic characteristics relate to properties of the object of study, which is an important aspect in the choice of methods, tools and modes of testing on the effects of vibration. Information-measuring system consists of control system information-measuring systems, multi-channel vibration installation induction vibration measuring converters (VIP), digital generator, differential amplifier. The obtained experimental data were compared with the results obtained on a shaker ВС132 the classical consolidation of the research object on a vibrating table. The analysis showed the individual resonances on the shaker ВС132 are excited with much smaller amplitude. At a frequency of 200 Hz, the amplitude obtained on a shaker ВС132 75 % below the amplitude obtained on the developed IMS. In addition, the accuracy of determining the resonant frequencies of the IMS in the low frequency region increased by 5 % due to improved averaging of the measurement and the absence of pulsation due to the increased time of passage bass region of the frequency range.
Conclusions. Developed information-measuring system allows to determine the dynamic characteristics relate to properties of the object of study. This is an important aspect when choosing methods, tools and modes of testing on the effects of vibration. The use of independent excitation of the points of attachment of the object of research allows to excite resonances in all its forms in the studied frequency range.
