摘要
针对钻井过程中钻柱的旋转运动及扭转和横向弯曲振动形式的同时发生，分析和探讨了旋转状态下的钻柱耦合振动问题，建立了一个含回转项的旋转钻柱运动方程，并用近似方法解出了其动力响应的具体表达式。
In the light of the rotation and the simultaneous torsional and lateral bending vibration of the drillstring in drilling operation, the coupled vibration of the rotating string is investigated, a motion equation containing gyro-term for the string is established, and an approximate expression for the dynamic response of the drillstring vibration is derived.
