Structure optimization for magnetic equipment of permanent magnet retarder

Bingfeng JIAO, Desheng LI, Yunkang SUI, Lezhi YE

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4,   Pages 442-445 doi: 10.1007/s11465-010-0112-z

Abstract: main purpose of this research is to perform a magnetic analysis on the magnetic equipment of permanent magnetThe mathematical model of structure optimization is also built.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).
