Parametric approach to linear induction accelerator design

This paper analyzes the influences of the factors in a capacitor-driven multi-stage synchronous induction coilgun (SICG) and optimal combination of the design parameters based on orthogonal experiment design (OED). Finite element transient solver is used to calculate the motion characteristics of a multi-stage SICG. The muzzle speed is set to be the target of the optimization. System parameters (factors), levels and orthogonal array (OA) are determined by the order. Three optimization schemes are compared, including stage-by-stage optimization, section optimization and full optimization. Optimal combination of the three-stage SICG is obtained, as well as important order of factors. It shows that a set of comparatively better parameters and relatively higher efficiency could be achieved through orthogonal optimum. Wire diameter and coil diameter are the most important factors that influence the system efficiency of the launcher. Besides them, length of coil, trigger position and number of turns have less influence for the system in the important order. Section optimization could reduce the amount of computations compared to full optimization and a set of comparatively better parameters and relatively higher efficiency could be achieved. It is suggested to optimize a multi-stage SICG. How to choose the factors from lots of parameters is according to the engineering practice. Improper choices of the value in levels may cause unable to reach an optimum. The conclusion will be useful for coilgun design.

“…Haghmaram and Shoulaie present a literature review of the available methods to analyze the air-cored tubular linear induction motors used in electromagnetic launcher applications with a strong emphasis on the LIL [18]. By considering the arguments in [18], the most popular methods for modeling and analysis of the traveling magnetic wave linear induction launcher can be classified as Current Sheet Method [19][20], Mesh Matrix Method [21][22], Wavelet Transform [23], and Finite Element Method [24][25]. All the FEM models available in the literature for the LIL are two-dimensional.…”

This paper deals with the 3D FEM analysis of a novel magnetic levitation (maglev) train driven by an air-cored tubular linear induction motor. This new maglev system originates from Electromagnetic Launcher (EML) technology, especially the Linear Induction Launcher (LIL) type. Some 2D magnetic analyses based on current sheet model or transmission line approach for the LIL type launchers are available in the literature but this paper provides an alternative way to analyze LIL type of EMLs by using 3D Finite Element Method (FEM). The analysis examines into the variation of propulsion, levitation, and guidance forces induced in the moving part. It is expected that the possible results of this magnetic analysis will lead some new and important design considerations for the novel maglev system.

“…Current filament model (CF model), or mesh-matrix method is based on mutual inductance method, or circuit model and is a very valuable tool for transient analysing and evaluating the performance of an induction launcher [22]. We can understand the reasons for most of the departures from the sinusoidal stesdy-state model by taking into account four hurdles that prevent its attainment: (1) single phasing, (2) fiequency mixing, (3) damping, and (4) sectionalization [23].…”

“…The design process is made considerably easier and yields much better results when an optimizer is used. This iteratively calls the simulation model to fmd the best design [22]. The method Described in [22] used a parametric optimization routine to iteratively seek out effective designs within a parameter space restricted to interesting and realistic parmeters such as size, weight, voltage, and temperature rises.…”

In this paper, we review some major research results in Traveling Wave Tubular Linear Induction Motors technology, based on 'open literature"publications, which were obtained in the world in the last decades. One database analysis shows that coil launchers are covered in 68 of over 1000 electromagnetic launcher papers published, referred to 53 of them in this paper. The research program includes studies of history, types, applications, theories and analysis, design, and power conditioning of coil launchers with emphasising on traveling wave induction (Linear Induction Launcher) one. In the theories and analysis section, a preview i s given of current sheet model, current filament model, finite element method, and wavelet transform. In the design section, local and global optimisation algorithms and designing results is reviewed. In the fmal section, we review power conditioning of Capacitor Driven Coilguns and Generator Driven Coilguns, and concepts of "Magnetic Flux Compression" for generating pulses required to efficiently drive the coil launchers and LLDouMc+Fed Induction Launchers".
