Abstract:

On the basis of analyzing the failure forms of the sucker rod, the existence of the torsional vibration of the sucker rod was approved and its reason was found out. The up and down boundary and condition of the torsional vibration of the sucker rod was established in the light of the results. It provided the theoretical supports for the torsional analysis and its failure of the sucker rod.

Key words: sucker rod, torsional vibration, boundary condition, analysis
