 Authors: Proskurin A.V., Shlishevskiy A.V. Published: 21.12.2019 Published in issue: #6(129)/2019 Category: Mechanical Engineering and Machine Science | Chapter: Machines, Units and Processes Keywords: natural frequency of oscillations, form of natural oscillations, shock loading, spectral density, experimental studies, piezoelectric accelerometer

The task of studying the behavior of various structures under the influence of intense pulsed (shock) loads that arise during the operation of many modern structures, machines and devices remains relevant for many years. One of the stages of this study is to find the values of the natural frequencies of vibrations and design parameters that determine these values. To find the natural frequencies of oscillations of the body, which are four flanges connected by cylindrical shells, the finite element method and analytical solutions were used. An analysis of experimental studies. Determination of natural frequencies values and design parameters determining these values will allow evaluating the response of the structure to the loads acting during its operation, and making corrections to the structure that change the response of the structure, as well as will help to more accurately select the installation sites of piezoelectric accelerometers for recording drums accelerations
