Linear shock electromechanical converter of electromagnetic-induction type

Linear shock electromechanical converter of electromagnetic-induction type

Abstract

Purpose. Estimation of the efficiency of structural schemes of combined linear shock electromechanical transducer (LSET) of electromagneticinduction type with associated and independent displacement of anchors, taking into account force, speed and environmental indicators. Methodology. The mathematical model of LSET using the finite element method, which takes into account spatio-temporal electromagnetic and electromechanical parameters and indices, is developed and implemented in the Comsol Multiphysics software package. The integral efficiency index has been introduced, taking into account the power, speed, energy, and environmental (induction of the magnetic scattering field) indicators. Results. It is established that in the induction-type LSET, electromagnetic processes occur at a higher speed and at higher electromechanical values compared with the electromagnetic-type LSET. In LSET electromagnetic-induction type with associated anchors, the character of electromechanical characteristics is similar to the character of the corresponding character of the LSET induction type, but with higher indices. In LSET with unconnected anchors, an electrodynamics repulsive force acts on the electrically conducting armature, the maximum magnitude of which is approximately an order of magnitude higher than the electromagnetic force of attraction acting on the ferromagnetic anchor. For all variants of the evaluation strategy, the design of the electromotive-induction type LSET is more effective than the induction and electromagnetic-type LSET. A constructive scheme of the electromagnetic-induction type LSET with unconnected anchors is proposed, which provides a linear-rotary motion of the impact element. Originality. For the first time, the LSET electromagnetic-induction type design with unbound electrically conductive and ferromagnetic anchors is proposed and justified, which allows to provide linear-rotary motion of the impact element. Practical value. It is established that in the LSET electromagnetic-induction type with unconnected anchors on the electrically conducting armature the electrodynamics repulsive force operates, the maximum value of which is approximately an order of magnitude higher than the electromagnetic force of attraction acting on the ferromagnetic armature. This causes a lower speed of the ferromagnetic armature than the speed of the electrically conductive armature.

При помощи интегрального показателя эффективности, учитывающего силовые, скоростные, энергетические и экологические показатели установлено, что ЛУЭП электромагнитно-индукционного типа более эффективен по сравнению с ЛУЭП индукционного и электромагнитного типов. Предложена конструктивная схема ЛУЭП электромагнитно-индукционного типа с несвязанными якорями, обеспечивающая линейное и поворотное движение ударного элемента.
