Abstract

In this paper, we investigated an optimized transmission line method (TLM) using an equivalent circuit model and relaxation method to calculate the nonlinear magnetostatic field in an axisymmetrical actuator with permanent magnet. A Newton-Raphson (N-R) preconditioner, parallel reflection phase in TLM and a CPU-based parallel triangular solver using level scheduler are exploited to accelerate the computation in each nonlinear iteration step. Compared with conventional N-R iteration, the optimized TLM algorithm greatly reduces the computation time more than 10 times. In addition, the magnetic field distribution and the electromagnetic force of the studied actuator are calculated by the proposed method in this paper, and the simulation results are validated through experiments.
