根据机械振动理论，提出了起升加速度作用下的钻柱振动微分方程及其解法。找出了动载系数与起升加速度之比随时间的变化规律。结论认为，当起升加速度较大时，其起升动载不可忽视。
According to the theory of mechanical vibration, the differential equations of drilling vibrations and their solutions under the action of hoisting acceleration are proposed. The change law of the ratio of dynamic load coefficient and lifting acceleration with time is found out. The conclusion is that when the lifting acceleration is large, its lifting load can not be neglected.
