Inverse problems in the design of electromagnetic mechanisms of ground vehicle magnetic levitation systems

Abstract

An increase in the speed of ground transport, along with an increase in its safety, economic efficiency, environmental friendliness, and for passengers - the comfort of transportation, is one of the most important goals of progress in this area of human activity. One of the main innovative phenomena of land transport that meets these goals has been the creation of high-speed ground transport based on magnetic levitation. The purpose of this work is to develop an effective method for solving inverse problems of designing electromagnetic mechanisms for systems of magnetic levitation and lateral stabilization of ground transport. To achieve this goal, the following tasks were set and solved. Statements of conditionally well-posed inverse problems of designing electromagnetic mechanisms of ground transport magnetic levitation systems with objective functions and constraints that take into account the features of the magnetic system are formulated. A numerical method and a computational algorithm for solving the optimal design problem have been developed, which makes it possible to reduce the time of its solution. The advantage of the algorithm is the presence in it of the procedure for minimizing the mass of the electromagnetic mechanism. Experimental studies of the developed method for solving inverse problems have been carried out. The application of the method has been demonstrated on a specific electromagnetic mechanism, however, it can also be used in the design of other technical devices.
