Technological vibrating machines - new approaches in dynamic state estimation and adjustment. Part I

Abstract

The paper deals with the methodological foundation for the processes of estimation, adjustment, monitoring and changing of the dynamic states of mechanical oscillatory systems. The purpose of the proposed studies is to develop a method for estimation and variation of the dynamic properties of technical objects on the basis of additional ties introduction into basic mechanical vibrational structures. It is shown that such ties can be implemented by lever mechanisms introduced into the original structure. The methods of structural mathematical modeling are used, within which a mechanical oscillatory system is treated as a dynamically equivalent automatic control system. A method of mathematical modeling has been developed and technologies for constructing the transfer functions of the system have been proposed. The concept of inter-partial tie transfer functions is introduced on the basis of which a technology for determining analytical relationships defining the possibilities of obtaining vibration fields with specified properties is developed. The choices for vibration field adjusting parameters are offered. The features of dynamic properties and new dynamic effects reflecting the specificity of dynamic interactions of system elements are studied. The results of numerical experiments are provided.
