| 中文摘要:在极地钻探技术领域中，铠装电缆式电动机械取心钻具应用广泛，优化、设计可靠的反扭装置，提高其反扭力矩，是冰下基岩电动机械取心钻具钻进成功的关键所在。为了分析反扭装置的全部性能，提出了基于数字化虚拟样机RecurDyn的仿真方法。反扭装置的组成机构是平面六杆机构，在RecurDyn中导入由inventor软件建立的反扭装置几何模型进行运动仿真及分析。介绍了利用RecurDyn软件来实现平面六杆机构（反扭装置）运动仿真及分析的方法和步骤。以反扭装置作为研究对象，在RecurDyn/post模块中，用动画来表现反扭装置的运动过程，用图表来反映运动仿真的结果。仿真的结果证明反扭装置设计的科学性、合理性以及实用性，可以实现预定位置变化，满足极地钻探中平衡钻进的要求。 |

| Abstract:In the field of drilling technology in the polar regions，the coring tools of armored cable type electric machinery are widely used. Optimizing and designing the anti-torque system to improve the anti-torsion is the key for the successful core drilling in sub-glacial bedrock with electric machinery coring tool. In order to analyze all the performance of anti-torque device，the simulation method based on digital virtual prototype RecurDyn is proposed. Anti-torque device is composed of planar six-bar mechanism; the inventor software is introduced into RecurDyn to establish the geometry model of anti-torque device, by which the motion simulation and analysis are carried out. The paper introduces the method and procedures of how to use the RecurDyn software to realize the motion simulation and the analysis on the planar six-bar mechanism (anti-torque device). With anti-torque device as the research object, the motion of anti-torque device is showed by animation in RecurDyn/post module and the chart is used to reflect the result of motion simulation, by which the science, the rationality and the practicability of anti-torque device design are proved and the predetermined position changing can be determined to satisfy the request of balance drilling in polar regions. |
