理工大学毕业论文les drilled anchor holes and trenches of the pilot hole, etc drill in other areas of geotechnical engineering, tunnel drilling equipment And technology can be used for the dam foundation Slope control of geological disasters in the deep foundation of support, as well as industrial and commercial transport and military aspects of underground construction.
By introducing the top drive drilling rigs, according to mechanical vibration theory, the obtained differential equations of motion, and for the development of the actual situation, the reasonable determination of the top drive system, the amplitude, excitation frequency, the exciting force, eccentric torque, and other major parameters。
According to the vibration of the top drive the process of dynamic analysis, based on this prototype, get a box center of mass position, eccentric, and exciting force centroid position changes with time parameter curves on the top drive system to achieve a virtual Prototype dynamic simulation analysis。 Application of ANSYS software to
the top drive system, load-bearing component hammer finite element analysis, using this analysis whether the top drive system design to meet the requirements for the study of the production prototype provides a theoretical basis. Meanwhile, the rig air operation conducted experiments to test and verify the production of top drive structure design.
Keywords: drilling rig; top drive design; virtual prototype; dynamic simulation analysis

2(1 顶驱装置的概述
顶驱的全称为顶部驱动钻井装置TDS(TOP DRIVE DRILLING SYSTEM)，是美国、法国、挪威近20年来相继研制成功的一 种顶部驱动钻井系统。它可从井架上部空间直接旋转钻杆，沿专用导轨向下送进，完成钻杆旋转钻进，循环钻
