在磁后坐发电机的工程设计中,主要通过磁路解析法计算初始位置线圈磁通来估算空载电压,大量的直接近似处理使得最终计算结果误差较大.为此,引入有限元法对磁后坐发电机的二维轴对称瞬态磁场进行场路耦合分析.运用有限元分析软件Ansoft进行仿真,输出电压与对应试验结果对比误差较小,说明有限元法用于磁后坐发电机工程计算,精度较高,并且能得到工作中的瞬态信息,可以代替以前的方法.

In the design of magnetic setback generator, voltage of coil in open circuit is usually estimated by magnetic circuit analysis which may lead to an inaccurate result because of amount of direct approximate process-ing. Therefore, the FEM (finite element method) is introduced to do the coupled field-circuit analysis for 2D axi-symmetric transient magnetic field. By using the Ansoft software, the simulated output voltage achieves high pre-cision compared with the test result,which shows the FEM can be used as a more effective method for magnetic setback generator design.
