四、振动及强度计算对钻机起升时的振动问题,国外已运用拉普拉斯变换,求解气胎离合器挂合中打滑段内传动装置二质量计算图的运动方程,求得打滑结束时离合器摩擦力矩发生了阶梯式的减小,这种扭矩波动在起升部件中引起很大的振动。就整个钻井起升系统而言,内 Fourth, the vibration and strength calculation Rigging when the vibration problems, foreign Laplace transformation has been used to solve the air fetus clutching clutch in slippery segment two mass calculation diagram of the equation of motion, obtained at the end of slip clutch Friction torque stepped down, the torque fluctuations in the lifting components cause a lot of vibration. In terms of the entire drilling and lifting system, within
