The issues of developing mathematical models of mechanical systems with dynamical absorbers through links coupling
Khomenko A.P., Eliseev S.V., Artyunin A.I.
The paper deals with a general theory of lever dynamical vibration absorbers in mechanical systems intended to protect machinery and equipment from vibration and stresses. Desirable effects will be achieved by making proper couplings between the system links which results in reducing the number of freedom degrees of the system movement. Possibilities of using several systems of coordinates for describing the system dynamical properties depending on the element location and support are discussed. The paper considers the ways of eliminating some coordinates of relative movements provided they could be equal zero under specific conditions. Such approximations form link couplings and mechanisms in vibration system structure which can change the system dynamics. New means for controlling vibroprotection system dynamics could be developed. A number of examples are given based on mathematical modelling.
Keywords: vibroprotection systems, dynamical absorbers, lever mechanisms.

Determination of karst collapse intensity from incomplete data
Sharapov R.V.
The paper deals with the definition of karst collapse intensity. The technique for determining the intensity of karst formation and collapse on the basis of calculation and probabilistic method is given. In reality, karst col-lapse formation is affected by a great variety of natural and anthropogenic factors. Each factor can vary quite widely. Certain combinations of factors can cause karst process activation, while other combinations are not able to bring the natural system out of balance. The paper describes a technique for determining karst collapse intensity from incomplete data. It uses karst processes monitoring data in the area and monitoring data of areas with similar values of the most significant factors leading to the karst collapses.
Keywords: karst collapse intensity, karst, karst collapse.

Technical diagnostics of the contactless transformer sensors blocks of geodynamic monitoring system
Orekhov A.A., Dorofeev N.V., Romanov R.V.
Monitoring systems of geodynamic objects built on the basis of multi-polar electrolocation equipment are widely used now due to the increased danger of technogenic catastrophes causing instability of geological structures. These systems consist of emitting electrodes and receiving contactless transformer sensors located directly in soil. Characteristics of the block components change over a wide range and sometimes fail due to severe service conditions of the sensors. The purpose of this paper is to develop technical diagnostics subsystem of the contactless transformer sensors blocks, allowing to identify characteristic deviations of block components from operational ones when operating geodynamic monitoring system on the object under control. It is important to identify block component failures transferring data to the central station.
Keywords: environmental monitoring, geoelectric control, geodynamic object, technical diagnostics.
