给出了灵敏度对几何或物理参数的计算及其在优化过程中的应用。磁场计算采用二维有限元方法。用拟牛顿法确定极小化方向，用罚函数处理参数上下界的约束。在一维极小化中采用了三次逼近方法。给出了在保持继电器模型所需力的同时使电流密度(J/C/)最小化的例子。&gt；
The calculation of the sensitivity versus a geometric or physical parameter and its use in an optimization process are presented. The 2-D finite-element method is used in the magnetic field calculation. The quasiNewton method is used to determine the direction of minimization, and the constraints of upper and lower bounds of parameters are treated by the penalty function. A cubic approximation method is used in the unidimensional minimization. Minimization of the current density (J/sub c/) while keeping the force desired for a relay model is presented as an example. >
