摘要

在石油钻井行业中,振动筛的平稳运行在固液控制和钻井液回收中起着至关重要的作用。由于机械耦合,振动筛的表面容易产生不平衡摆动,使运动轨迹与质心处的情况不一致,从而影响筛分效率。为了揭示振动系统不平衡摆动的原因和轨迹平衡特性(tec)的原理,研究了椭圆轨迹双电机振动系统中偏心转子的自同步特性。用拉格朗日法确定了振动系统的运动微分方程。然后,采用小参数平均法和Routh-Hurwitz准则分别确定了振动系统的同步条件和稳定条件。随后,通过数值讨论验证了结构参数对同步稳定性的影响。通过不同结构参数下的动力学仿真与实验结果对比,验证了理论研究的有效性。最后,通过对实验中不同测点轨迹的分析,得出了如何减小不平衡摆动和保持振动系统tec的相关结论。系统的椭圆轨迹形式受振动体内电机安装角度和安装距离的影响最大,而受电机安装偏转角度和安装偏移距离的影响较小。另外,减小振动系统的摆角,即增大稳态激振器的安装角,减小激振器的安装距离,使振动体的椭圆轨迹处于良好的平衡状态。

Theoretical and experimental study for implementation of the elliptical trajectory in dual-motor vibration system
In the petroleum drilling industry, the smoothly functioning vibrating screens play a critical role in control of solid–liquid and recovery of drilling fluid. Due to the mechanical coupling, the surface of the vibrating screen tends to produce unbalanced swings, which makes the motion trajectory inconsistent with the situation at the center of mass, thus affecting the screening efficiency. In order to reveal the reasons for the unbalanced swings of the vibration system and the principle of the trajectory equilibrium characteristics (TECs), the self-synchronization characteristics of two eccentric rotors (ERs) driven by elliptical trajectory dual-motor vibrating system are investigated. The kinematic differential equations of the vibration system are determined by the Lagrange method. Then, the conditions of synchronization and stability of the vibration system are determined, respectively, by the small parameter average approach and the Routh–Hurwitz criterion. Subsequently, the impact of the structural parameters about the synchronization stability is examined by numerical discussion. Furthermore, the effectiveness of the theoretical research is confirmed by comparing the results between dynamics simulation and experiment under different structural parameters. Finally, by focusing on the analysis of the trajectories of different measuring points in the experiment, the relevant conclusions on how to reduce the unbalanced swings and maintain the TECs of the vibration system are obtained. The elliptical trajectory form of the system is most affected by the motor installation angle and installation distance in vibrating body, while less affected by the installation deflection angle and installation offset distance between the motors. In addition, the elliptical trajectories of the oscillating body are in a good equilibrium when reducing the swing angle of the vibration system, in other words, increasing the installation angle and reducing the installation distance of the exciters in the stable state.
