The Stress Analysis of Joint Connecting Bolt of Submersible Electric Pump

Abstract

Submersible electric pump units are connected by bolts. This paper uses finite element analysis method to simulate how the pump joint bolt behave when it transmit torque.In this paper, temperature method is adopted to simulate the bolt preload and axial deformation.It also used to analyse and calculate the limited value when submersible electric pump units transmit torque under different preload. All of this provide the designing of connecting bolt preload and construction with theoretical basis.
