MATHEMATICAL MODELING OF THE VIBRATOR TORSIONAL VIBRATIONS
In this work, we analyzed electro-mechanical system electromagnetic vibrator to generate torsional vibrations. The object of study is the electromagnetic vibrator of torsional vibrations. Purpose is to obtain power characteristics and timing diagrams of operation of such vibrator through a mathematical numerical simulation. In the article the urgency of use of vibrating technology in various fields, such as verotrack concrete, seismic and enhanced oil recovery wells. The design and principle of operation of the vibrator of the electromagnetic type, which produces torsional vibration on the ground. The mathematical model of the Electromechanical system of the vibrator and the key assumptions adopted for its construction. The model includes the interconnected state equations for electrical and mechanical systems and provides formulas for calculation of variables included in these equations. For the equations of the dynamics of the vibrator limitations of their application. Listed and explained the numerical values of the inputs used for the simulation. Modeling (the solution of the system equations of state) of the system implemented in the dynamic simulation of matlab/simulink. The results of the numerical solution is given in the form of time diagrams, the results of their analysis and conclusions. The article may be of interest to professionals working in the areas of vibration engineering, seismic exploration, the field of enhanced oil recovery wells and conducting mathematical modeling of Electromechanical and other systems, including specialized software packages. The work described in the article, were conducted in the NIL-6 «VIEMTEX» (vibroimpulsny electromagnetic technique), Togliatti state University (Togliatti, 2011-2014). They are a logical continuation of works on creation of electromagnetic and induction-dynamic seismotechnika successfully used in seismic exploration at present.
