Features of dynamic properties of mechanical oscillatory system at power and kinematic indignations

Abstract

Distinctions in reactions of mechanical oscillatory system at power and kinematic harmonious influences are considered. Feature of approach is that in structure of system there is an additional ties in the form of the mechanism working in paralleling with an elastic element. The method of creation of mathematical models of the structural type, based on Laplace's transformations is offered. The structural model of initial mathematical system is presented by the block diagram of the equivalent automatic control system in the dynamic relation. Possibilities of an assessment of features of dynamic properties of the systems formed by various indignations through transfer functions are shown. Analytical ratios of parameters of the system, allowing consideration of three modes of dynamic interactions at kinematic indignations are offered. Conditions of coincidence or equivalent action of power and kinematic influences are received. Results of numerical modeling of dependences of adjusting parameters from geometrical characteristics of the mechanism are given.
