摘要: 为了准确掌握微球极板在测井作业过程中的贴壁情况,保证微球聚焦测井的顺利高效进行,应用闭环矢量链法建立推靠系统主传动机构的运动学模型,进行运动学求解分析,以此为基础,对推靠系统各杆件机构进行静态动力学分析。推导出了微球推靠系统在不同约束状态下各传动部件的运动、动力约束方程。重点研究了微球极板、链接臂上的两处柱销滑槽高副机构的运动规律以及推靠极板、推靠内臂的动力性能参数。通过ADAMS建立了微球推靠系统的多刚体运动及动力学仿真模型,分析了推靠系统的运动及动力性能。通过仿真结果与数理模型的计算比对,校验了所建立微球推靠系统数理模型的正确性。同时,得到了微球推靠系统各传动机构的动力参数曲线及运动规律。

Abstract: To accurately understand the wall contact characteristics of microsphere plate during logging operation and to ensure stable and efficient microsphere focusing logging, a kinematic model of the primary transmission mechanism of the sidewall contact system was established. The model carried out kinematic computations by adopting the closed-loop vector chain method. Based on the above, static dynamic analysis was carried out for each bar member in the sidewall contact system. Motion and dynamic constraint equations governing all the transmission members of the microsphere sidewall contact system under different constraints were derived. The motion pattern of the higher pair mechanism of two pin chutes on the microsphere plate and the link arm were studied extensively; Further, the dynamic performance parameters of the sidewall contact plate and arm were also studied. Through ADAMS, a kinematic and dynamic simulation model of multi-rigid body was established for the microsphere sidewall contact system, and the kinematic and dynamic performances of the sidewall contact system were analyzed. By comparing the simulation results with those from the mathematical model of the microsphere sidewall contact system, the model was verified. Furthermore, the dynamic parameter curve and motion pattern of each transmission member of the microsphere sidewall contact system were obtained.
