Chernyshov M. Elements of constant magnet systems for vibration devices

The subject investigation is the elements of systems with permanent magnets and low frequency electromagnetic vibrators. The purpose of investigation: construction of mathematical models and methods of analytical and numerical account of magnetic fields, of power characteristics and of dynamics of the systems' elements move for a sound choice of the basic technical parameters of vibration devices and their optimization. Method of investigation and instrumentation: analytical methods of a solution of differential equations, asymptotic method of the theory of non-linear oscillating and method of a statistical linearization. Theoretical results and novelty: the theory of the methods and schemas of analytical and numerical account of magnetic fields, of power and dynamic characteristics of systems' elements and schemas of low frequency electromagnetic vibrators is developed. Practical results and novelty: the base mathematical models of the systems' elements and low frequency electromagnetic vibrators are developed. An object and extent of introduction: the methods of account of low frequency electromagnetic vibrators for Ukrainian Institute of transformer building are introduced. Efficiency of introduction: the technical and economic indexes of low frequency electromagnetic vibrators are improved. Sphere of usage: electrical technology.
