| 中文摘要: |
| 用Workbench建立深海电机密封圈的有限元模型，计算密封圈在安装和工作过程中的受力和变形情况。结果表明：安装过程中密封圈所受应力先增大后减小，壳体移动距离为0.17 mm时，密封圈在Y方向所受应力最大；随着壳体继续运动，密封圈所受应力逐渐减小；当壳体移动距离为0.86 mm时，密封圈所受应力几乎不再变化；密封圈在X方向所受应力可表示预紧力，电机正常工作时密封圈所受最大应力大于安装时的预紧力，可以保证电机正常工作。 |
| 英文摘要: |
| The finite element model of the seal ring of deep sea motor was established by Workbench to calculate the force and deformation of seal ring during installation and operation. The results showed that the stress of the sealing ring increased firstly and then decreased during installation. When the shell moved at a distance of 0.17 mm，the stress of the sealing ring was the largest in Y direction. As the shell continued to move，the stress on the seal ring gradually decreased. When the movement distance was over 0.86 mm，the stress on the seal ring changed little. The stress on the seal ring in X direction could indicate pre-tightening force. When the motor was running，the biggest stress of the sealing ring was larger than the preloading force at the time of installation，which could ensure that the motor was working properly. |
