| 摘 要： | 当转动球铰摩阻力矩较大时,意味着落架后,转体部分在自身的不平衡力矩作用下未能发生转动,此时需要靠安装在北侧和南侧转盘上的千斤顶施加顶力方能使转体部分转动。

| Abstract: | When the frictional torque of rotation spherical hinge is great,it means the swivel can′t rotate under the effect of self unbalance torque.Therefore,the jacks which are fixed on the turntables at both north and south sides should exert jacking force to make the swivel rotate. |

| Keywords: | unbalance torque frictional torque swivel |
