Features of Vibration Machines with the Introduction of Additional Links in the Form of Lever Mechanisms

Abstract

The methods of the estimations of features of oscillation damping, taking into account the specifics of dynamic states of objects with several degrees of freedom, which have a spatial metric, are proposed. The proposed method for constructing mathematical models based on the use of structural diagrams that are dynamically equivalent to automatic control systems has the ability to display the processes of forming dynamic constraints and to detail the manifestation of their properties with regard to specific structural and technical forms of mechanisms. The possibility of constructing structural mathematical models for objects with two degrees of freedom, in which dynamic damping modes are provided by introducing and using additional constraints implemented by lever mechanisms, is considered. It is shown that the introduction of additional constraints in the form of lever mechanisms into the structure of mechanical oscillatory systems for various purposes significantly changes the dynamic properties of the systems, in particular, in problems of vibration protection.
