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。
In the field of polar drilling, armored cable electromechanical coring tools are widely used to optimize and design reliable anti-twisting devices and improve their anti-torque, which is successful in the drilling of ice-core electric-mechanical coring tools. The key. In order to analyze the full performance of the anti-torsion device, a simulation method based on digital virtual prototype RecurDyn is proposed. The anti-twist device is composed of a planar six-bar mechanism. RecurDyn is used to import the geometric model of the anti-twist device created by inventor software for motion simulation and analysis. The methods and steps of using RecurDyn software to simulate and analyze the movement of a planar six-bar mechanism (anti-twist device) are introduced. With the anti-torsion device as the research object, in the RecurDyn / post module, an anti-torsion device is used to represent the motion of the anti-twisting device, and the chart is used to reflect the result of the motion simulation. The simulation results prove that the design of anti-twist device is scientific, reasonable and practicable, which can realize the predetermined position change and meet the requirements of balanced drilling in polar drilling.
