在传统的磁力矩器设计过程中,仅对其支架位置进行了简化设计,未进行严格的解析及数值模拟计算,且未考虑磁力矩器支架的几何参数对其应力水平的影响。针对此问题,文章分别从解析计算和有限元数值模拟两个方面着手,研究了磁力矩器的支架位置以及支架几何参数对其应力水平的影响,给出了磁力矩器的应力水平关于不同几何参数的变化趋势。在这些几何参数中,螺栓直径对于改善应力分布的作用最为明显,因此当应力不满足要求时可以通过增大螺栓直径快速地降低整个磁力矩器的应力水平。 In the traditional magnetic torque device design process, only the simplified design of the position of the bracket, without rigorous analysis and numerical simulation, and did not consider the geometrical parameters of the magnetic torque supporter on the stress level. In order to solve this problem, the paper studies the influence of the position of the holder and the geometrical parameters of the holder on the stress level from two aspects of analytical calculation and finite element numerical simulation, respectively. The stress levels of the magnetic torque converter are given in terms of different geometric The trend of the parameters. Among these geometrical parameters, the bolt diameter is most effective in improving the stress distribution, so the stress level of the entire magnet torque can be rapidly reduced by increasing the bolt diameter when the stress is not sufficient.
