| 对采用电磁力驱动的两种锁制器设计方案进行了比较。计算结果表明，在同样的舵面干扰力矩载荷作用下，锁销式方案需要的电磁吸合力仅为摩擦式方案的9.25%。对锁销式锁制器采用滚动摩擦方法进行改进后，其所需的电磁力进一步降低到仅为摩擦式锁制器的6.32%。由于所需电磁力大为减少，故可大幅度降低线圈的尺寸和功耗。而大功率电动舵机的锁制器内部线圈占锁制器质量的80%以上，故采用该改进方案，可以明显减小系统的质量和功耗。 |

| Abstract: |
| Two design proposals of locking-apparatus driven by electromagnetic force were compared in this paper.The calculation result shown that, compare to friction-plate conformation, the electromagnetic force request in the pin conformation was only 9.25% under the same rudderpost moment.After locking-apparatus was improved by a rolling friction structure, the electromagnetic force of the pin conformation can be reduced to just 6.32% of the friction-plate conformation request.Due to the electromagnetic force request reduced, the size and power of the coil can be much more reduced.In the high-power electromechanical actuator, the weight of the coil was more than 80% of the whole locking apparatus system, so the weight and power can be significantly reduced by using the improve structure proposed in this article |
