Drill string vibration is the main reason for its failure and fatigue damage.Employing the dynamics theory and its basic differential equations with a reasonable assumption, the longitudinal vibration model of the drill string is established and analyzed by means of ANSYS code.The rule of the drill string vibration is obtained.Results of this work may provide some guidance for design and operation of the drill string.
