Structural dynamics modification for derrick of deep well drilling rig based on experimental modal test and frequency sensitivity analysis
A statically designed derrick of deep oil well drilling rig may have poor dynamic characteristics, which can cause earlier structure failure of the drilling rig and harsh working condition. One such designed derrick is found to vibrate severely in operation while the rotation speed of rotary table i...
