Abstract:
      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.
