项目摘要

1. Construction of CAD systems and development of 3-D automatic mesh generation system3-D magnetic field analysis can be calculated accurately using graphic user interface systems. It is necessary to develop the 3-D automatic mesh generation system to realize the 3-D analysis. So, we constructed CAD systems to recognize the shape of motors visually using work stations.2. Development of 3-D magnetic field analysis systemIt is necessary for the optimum design of motors to clarify the time variations of flux distributions and rotation angle of the armature. Specially, the finite element mesh that is used for the dynamic analysis have to be reconstructed according to the rotation of the rotor. So, we developed the virtual design system for various kind of motors such as synchronous motors and induction motors.3. High speed visualization system of analyzed results using animationsWhen we analyze the characteristic of motors, it is important to recognize these results accurately for designers of motors. It is very difficult to understand the results of dynamic characteristics, because these outputted data are very large. Therefore, the animation of dynamic characteristics such as the flux distributions and motion of the rotor is very useful for designers of motors. To realize this visualization, we constructed the animation system to express the analyzed results using work stations.

1. CAD系统的建立和三维网格自动生成系统的开发利用图形用户界面系统可以精确地计算三维磁场分析。为了实现三维分析，需要开发三维网格自动剖分系统。因此，我们建立了CAD系统来识别电机的形状视觉使用工作站.三维磁场分析系统的开发电机优化设计需要弄清电枢磁场分布和电枢转角随时间的变化规律。特别地，用于动力学分析的有限元网格必须根据转子的旋转来重构。为此，我们开发了同步电机、感应电机等各种电机的虚拟设计系统.分析结果的动画快速可视化系统在对电机特性进行分析时，准确地识别分析结果对于电机设计人员来说是非常重要的。动态特性的结果很难理解，因为这些输出的数据非常大。因此，动态特性的动画，如磁通分布和转子的运动是非常有用的电机设计者。为了实现这种可视化，我们构建了动画系统来表达分析结果使用工作站。
