采用连续介质力学的物质导数概念和设计灵敏度分析的伴随变量法来表达形状变化与目标函数变化的关系。推导了二维电磁系统中铁与空气界面变化的显式灵敏度公式。利用现有的有限元规范进行了灵敏度分析。将灵敏度分析应用于四极杆的极点优化。>
The material derivative concept of continuum mechanics and the adjoint variable method of design sensitivity analysis are used to express the relation between the change of shape and that of the objective function. The explicit sensitivity formula for the interface variation between iron and air is derived in a two-dimensional electromagnetic system. Implementation of the sensitivity analysis is carried out with existing finite element codes. The sensitivity analysis is applied to the pole optimization of a quadrupole. >
