【摘要】：在现代化的科学钻探过程中，自动化、智能化程度高的现代化石油设备得到了越来越广泛的应用。提高起下钻过程中钻具之间的连接与拆卸效率和安全性是保证科学探测迈向现代化的重要一环。为了适应这样的要求和趋势，我国国土资源部主导了“深部探测关键仪器装备研制与实验(Sinoprobe-09-05)”项目。以项目为依托设计和研制了一款新型全液压智能化铁钻工产品。本文主要利用理论分析和计算机仿真的研究手段对新型铁钻工伸展装置的机构性能进行研究，具体的研究内容归纳如下： 1.伸展装置的运动分析根据伸展装置的工作原理，将其简化成为一个平面机构。为研究伸展装置的运动特性，利用平面机构运动分析的杆组分析方法，建立伸展装置的运动学数学模型，并利用Matlab软件进行求解，得到了伸展装置的运动特性曲线。 2.伸展装置的动态静力分析考虑到铁钻工的钳体质量较大，惯性力对机构受力影响显著，因此为研究伸展装置的力学特性，需对其进行动态静力分析。依次对伸展装置的各个构件建立平衡方程，联立这些方程可以得到一个18元的线性方程组。利用Matlab软件对此方程组进行求解，得到伸展油缸的受力曲线。 3.伸展装置的动力学仿真分析为了校验理论分析的正确性，也为了得到更为真实和精确的运动学和动力学结果，利用ADAMS软件建立伸展装置的动力学仿真模型，对铁钻工的伸展过程进行仿真分析。通过仿真求解得到伸展装置的运动和受力曲线，并对仿真结果进行了分析和解释。 4.伸展装置的静力学仿真分析利用ANSYS Workbench软件对伸展装置的关键受力部件进行静力分析，得到支撑臂和伸展臂在最大负载情况下的受力和变形情况，校验了机构的安全性和可靠性。
[Abstract]:In the process of modern scientific drilling, modern petroleum equipment with high degree of automation and intelligence has been applied more and more widely. Improving the efficiency and safety of connection and disassembly between drilling tools is an important step to ensure the modernization of scientific detection. In order to meet this demand and trend, China's Ministry of Land and Resources has led the project of "the development and experiment of key instruments and equipment for deep exploration, Sinoprobe-09-05". Based on the project design and development of a new type of hydraulic intelligent iron drilling products. This paper mainly uses the theoretical analysis and computer simulation research means to study the mechanism performance of the new type of iron drill stretching device. The specific research contents are summarized as follows: 1. Motion Analysis of stretching device According to the working principle of the stretching device, it is simplified as a planar mechanism. In order to study the kinematic characteristics of the extender, the kinematics mathematical model of the extender is established by using the bar group analysis method of the kinematic analysis of planar mechanism, and the kinematic characteristic curve of the extender is obtained by using Matlab software. 2. Dynamic static analysis of extender Considering that the forceps of the iron-drillers have a large body mass and the inertia force has a significant effect on the mechanical properties of the mechanism, dynamic static analysis is needed to study the mechanical properties of the extender. The equilibrium equations of each component of the extender are established in turn, and a linear system of 18 elements can be obtained by combining these equations. The Matlab software is used to solve the equations and the stress curve of the extended cylinder is obtained. 3. Dynamic Simulation Analysis of stretching device In order to verify the correctness of the theoretical analysis and to obtain more real and accurate kinematics and dynamics results, the dynamic simulation model of the extender is established by using ADAMS software, and the stretching process of the iron drill is simulated and analyzed. The motion and force curves of the extender are obtained by simulation, and the simulation results are analyzed and explained. 4. Static Simulation Analysis of stretching device The static analysis of the key force components of the extender is carried out by using ANSYS Workbench software, and the stress and deformation of the supporting arm and the extension arm under the maximum load are obtained, and the safety and reliability of the mechanism are verified.
