Head Bazhenov V.A., Registration Date 05-02-2002 Organization Kiev National University of bildiny and tecture popup.description2 In the course of scientific research the technique for mathematical model constructing was developed. This technique adequately represents the response of systems with changeable structure to vibroimpact excitations. The technique is based on the direct approaches application. In accordance to these approaches a system of basis functions are determined using the mode shapes and weight states in a nonimpact system. Besides on the first stage of scientific research the numerical method for the analysis of the steady state vibrations in vibroimpact systems - method of continuations on the parameter- was developd. The method is oriented on research of multiparameter systems. The regimes of vibrations, in which there can be a rupture of velocities, that occur due to contact of an elastic system with a rigid obstacle, are analysed using the method.
