Possibilities of Dynamical Condition Control in Technical Systems under Vibration Excitation

Abstract

The method of mathematical models creation for the mechanical oscillatory systems containing mechanical movement transformation chains is suggested. A mechanical chain represents two symmetric groups of Assur interconnected with an elastic element and the device for transformation of movement of type of not self-slowing down screw mechanism. The features of the system dynamic properties are shown in the cases of power and kinematic excitation. The analytical ratios defining the dependence of the reduced masses and stiffness on the parameters of the introduced mechanisms are received. The analytical conditions for the possible change of the type of amplitude-frequency characteristics are received at kinematic excitation. It is shown that the introduced movement transformation devices can be used to setup the parameters of oscillations dynamic damping and to change the eigenoscillations frequencies.
