【摘要】：随着油田开发的需要,如何进一步提高双驴头游梁式抽油机运行可靠性进而发挥其显著的节能效果就显的十分重要。目前,抽油机的设计方法多以静态设计为主,在设计过程中往往采用的经验法,不能够准确的反映出动态载荷的作用。为解决这一问题,在研发过程中科研人员引入了虚拟样机技术,利用计算机建立抽油机的虚拟样机模型,对抽油机运行过程中的受力情况进行仿真分析,并取得虚拟样机的相关力学特征,用来优化改善抽油机结构。本文以CYJS10-5-37HB双驴头抽油机为研究对象,结合SolidWorks、Adams、ANSYS软件平台,研究刚柔耦合的建模方法,建立CYJS10-5-37HB双驴头抽油机刚柔耦合模型,进行动力学仿真分析,得到相关的仿真分析数据。本文主要进行的研究内容有:1.以柔性体建模理论为基础,建立CYJS10-5-37HB双驴头抽油机刚柔耦合模型,其中游梁与后驴头为柔性体模型。2.对建立的CYJS10-5-37HB双驴头抽油机刚柔耦合模型进行多体动力学仿真,最终得出关键部件(以后驴头和游梁为主)的力学特性参数。通过与传统计算结果对比,验证利用刚柔耦合模型求解结果的正确性,为其他更为复杂的机械系统的动力学仿真分析研究提供理论依据和参考。通过采用计算机技术对CYJS10-5-37HB双驴头抽油机复杂结构进行结构力学分析,是对仿真技术应用的进一步讨论,研究成果可以为抽油机设备的优化提供参考依据。
[Abstract]:With the development of oil field, it is very important to improve the reliability of double-donkey beam pumping unit and give full play to its remarkable energy-saving effect. At present, the design method of pumping unit is mostly static design. The empirical method used in the design process can not accurately reflect the effect of dynamic load. In order to solve this problem, the researchers introduced virtual prototyping technology in the process of research and development, established the virtual prototype model of pumping unit by computer, and simulated and analyzed the mechanical condition of pumping unit during operation. The mechanical characteristics of the virtual prototype are obtained to optimize and improve the pumping unit structure. In this paper, the rigid-flexible coupling model of CYJS10-5-37HB double donkey head pumping unit is established, and the dynamic simulation analysis is carried out based on the SolidWorks,Adams,ANSYS software platform and the rigid-flexible coupling modeling method of CYJS10-5-37HB double-donkey head pumping unit. Get the relevant simulation analysis data. The main contents of this paper are as follows: 1. Based on the theory of flexible body modeling, the rigid-flexible coupling model of CYJS10-5-37HB double donkey head pumping unit is established, in which the beam and the rear donkey head are the flexible body model. 2. The rigid-flexible coupling model of CYJS10-5-37HB double donkey head pumping unit is simulated by multi-body dynamics simulation. Finally, the mechanical characteristics of key components (donkey head and beam) are obtained. By comparing with the traditional calculation results, the correctness of the results obtained by using the rigid-flexible coupling model is verified, which provides a theoretical basis and a reference for the dynamic simulation and analysis of other more complex mechanical systems. The structural mechanics analysis of the complex structure of CYJS10-5-37HB double donkey head pumping unit by using computer technology is a further discussion on the application of simulation technology. The research results can provide a reference basis for the optimization of pumping unit equipment.
