Abstract

Operation of mechanical dynamic systems with adaptive hydrodynamic elements is investigated in this paper. Experimental research is performed taking the change of clearance between the rotors and bearing into account and investigating the effects of change of temperature and frequency of rotation of the rotor. Principle scheme of measurement is proposed. Matrix of planning of the proposed experiment is described. Principal system of measurement and method of analysis together with the proposed pattern of changes of searching parameters are presented and the obtained results of investigations are described in detail. Recommendations for the design of dynamic vibrating systems with adaptive hydrodynamic elements are provided and they are used in industrial applications.
