摘要：

Current filament models have been widely used for the electromagnetic analysis of induction launchers and electromagnetic devices. In this paper.two functions of the eigenvalues of the filament parameter matrix were determined in order to evaluate: - the errors on the system solution. induced by approximate calculations of the matrix parameters; - the influence on the solution, of a variation of the filament number of the discretization. These functions allow an estimate of the solution convergence, and accuracy, avoiding the numerical or analytical integration of the differential equation set of the system. The launcher has been modeled by means of a coordinate system coherent with the moving armature, with the hypotheses of piecewise constant velocity of the armature, in order to have not time dependent elements in the system matrix.
