摘要
装备的电磁拓扑数据结构包含点、节、边、面、简单体及复杂体对象数据结构。其建模步骤包括:选取装备建模区域及提取特征参数信息;将模型编号并划分层次;确立建模区域边界条件;定义关键区域和将特殊结点作为模型控制点;利用边界点和控制点对模型层面剖分,再利用这些点采用数值分析方法求层面上各未知点的参数值;对各个层面进行相交处理;将上下相邻的层面简并起来,构成完整的层块模型。
The electromagnetic topological data structures of equipment include point, node, boundary surface, simple body and complex body. Its establishing steps include： selecting model establishment area and extracting feature parameter information; giving models serial numbers and dividing layers; ensuring the boundary conditions of model establishment area; defining key area and considering special modes as the model control points; using boundary point and control point to divide model layer, then using these points and data analytical algorithm to acquire the parameter of unknown points; carrying out intersecting operation for every layer; and combing the adjacent layers to establish the integrate the layer module.
