ABSTRACT

The natural vibration modes of mechanical systems with different numbers of degrees of freedom are considered. The common vibration features of two- and multi-degree systems are compared. The similarities and differences between the parametrical dependencies and the possibility of change in vibration phases at varying parameters is considered.
