Its own spectrum band - a property of mechanical systems

Abstract

In experimentally and modelling, the results have been obtained, revealing the existence of the hardes tmode of broadband random vibration in function of the spectral width when it impacts on the mechanical system. During broadband random vibration there are extremums of tension in the material and vibration speed during the capture of «n» original frequencies of the system (n≥2). This fact indicates on presence of the “own bands” of the mechanical system, similar to the natural frequencies, but which appears at random loading.
