Dynamic response in the vibration-protection system assessment

Ermoshenko Y.V., Bolshakov R.S., Kaimov E.V.

The paper considers dynamic response identification method in mechanical vibration systems. Dynamic reactions between inertial-mass and connecting elements (springs and dampers) as well as reactions in contacts with bearing surfaces are determined on the basis of obtaining reduced rigidities. These parameters are determined during the transformation of structural models of initial design schemes. The approach under discussion is based on structural concept of mechanical vibration systems. They are transformed into corresponding structural schemes of automatic control systems. When you select an object for the constraint force calculation as the second-order integrator which corresponds to the object to protect in vibration-proof systems, for example, the feedback physically corresponds to the dynamic response. The examples are given. The technique for performing required changes and obtaining analytical relations for dynamic connection response determination is developed.

Keywords: method of definition of dynamic reactions at vibration influences, vibroprotection systems, transfer functions.
