Abstract. 

A methodology is being developed for estimating the dynamic states of technical objects of transport or technological purpose under conditions of vibration loads. Mechanical oscillatory systems with concentrated parameters are used as calculation schemes. A structural approach is applied, within the framework of which structural schemes of dynamically equivalent automatic control systems are aligned with mechanical oscillatory systems. Within the framework of the developed concepts, it is shown that the sets of dynamic states of parametric families of mechanical oscillatory systems can be characterized by finite sets of dynamic invariants.

Keywords: 

structural modeling, mechanical vibrations, connected perturbations, dynamic states, transfer functions, lever connections, vibration loads, solid, elastic elements.
