从球形压力容器在内压作用下的解析解出发进行分析,指出在现有著作和规范中,直接对沿壳体厚度变化的应力表达式沿壳体厚度的一条“处理线”进行一维积分求解厚壁球壳壁上的薄膜应力和弯曲应力的方法在概念上不够准确,会导致一定的额外误差。由此提出了在壳体的环形截面区域的一个“处理面”上进行二维积分来求解壳壁上的薄膜应力和弯曲应力的方法,在概念上是准确的,能够避免“处理线”法导致的额外误差。通过一个受内压厚壁球壳的弹性解析计算,说明新方法比原方法有明显的改进。

A brushless electrically excited synchronous generator (BEESG) with a hybrid rotor is a novel electrically excited synchronous generator. The BEESG proposed in this paper is composed of a conventional stator with two different sets of windings with different pole numbers, and a hybrid rotor with powerful coupling capacity. The pole number of the rotor is different from those of the stator windings. Thus, an analysis method different from that applied to conventional generators should be applied to the BEESG. In view of this problem, the equivalent circuit and electromagnetic torque expression of the BEESG are derived on the basis of electromagnetic relation of the proposed generator. The generator is simulated and tested experimentally using the established equivalent circuit model. The experimental and simulation data are then analyzed and compared. Results show the validity of the equivalent circuit model.
