Mechanics Model of Rotation Axis in Directive Rotary Steerable Drilling System

摘要:

在对指向式旋转导向钻井系统旋转轴结构和支承进行简化的基础上，建立了力学模型，给出了旋转轴在静态偏置状态下的转角方程、挠曲线方程、支撑反力及弯矩方程，对偏置力F作用点的位置进行了优化，为指向式旋转导向系统的工程设计和结构优化提供了理论计算依据。

Abstract:

The mechanics model was established on the basis of simplifying structure and supporting of rotation axis in directive rotary steerable drilling system. Rotation equation, deflection curve equation, reaction and moment equation of the rotation axis under the static offset condition were derived and the location of offset force F was optimized, which provide a basis for theoretical calculation on engineering design and structure optimization for directive rotary steerable drilling system.
