Theoretical bases and methods of the analysis vibroimpact processes in elastic systems of variable structure are developed. The method of solution continuation by parameter serves the numerical for the vibroimpact process analysis. Two variants of the vibroimpact processes analysis are offered: in the first variant the vibroimpacts movements task is formulated with the help of corresponding boundary conditions; in the second variant shock interaction is modeled with the help of the putting of nonlinear elastic force to contacting bodies . There were constructed the loading curves and the amplitude-frequency dependence of the vibroimpact processes in the elastic systems at the contact with the external obstacle and at the internal impact contact under the external periodic loading. There was fulfilled the stability analysis of the steadystate vibrations in such systems. There were fulfilled the short literature review and the problem analysis of the use of the pendulum vibroimpact dampers in high-rise buildings. There were created the differential equations of the movement of the system "object-pendulum dampfer" at modeling impact by two approaches: with the help of boundary conditions and use of nonlinear force characteristics of contact interaction. Efficiency of application is analyses and optimum parameters shock damper of mechanical system are determined at action of external stochastic loading.
