| Abstract: | The main purpose of this research is to perform a magnetic analysis on the magnetic equipment of permanent magnet retarder
(PMR) and optimize the structure of magnetic equipment with the commercial FEM software ANSYS and its design optimization
module. The FEM model is built as an axisymmetric model according to the characteristics of the structure of magnetic equipment.
Using this model, the magnetic field distribution and magnetic force are calculated by ANSYS. The mathematical model of structure
optimization is also built. The design variables are structural parameters including the dimensions of permanent magnets and
magnetic yoke, and the objective function is the magnetic force. The unconstrained optimization model takes the maximum value
of magnetic force as the objective. A first-order optimization method is used to determine the optimum design of this problem.
The optimization process works entirely with the ANSYS parametric design language (APDL). The design tools are used to understand
design space and the behavior of the dependent variables. It is shown that designing a structure with the ANSYS optimization
module and its design tools is an effective means to improve the structure. |
