摘要
采油螺杆泵立体模型的有限元分析涵盖几何、材料和接触三重非线性问题,且由于受到螺杆泵型面的复杂性和载荷的多样性影响,使得有限元模型的建立和有限元的计算难度较大,其方法尚不成熟.以GLB120-27型采油螺杆泵为例,利用SolidWorks软件建立螺杆泵三维实体模型;进行单轴拉伸实验,确定定子橡胶材料的Mooney-Rivilin模型常数;利用布尔运算分离密封带和定子内腔,并在它们之间建立接触对,实现定子内腔流体压力模拟;通过设置相关参数模拟定、转子之间的过盈配合,建立螺杆泵三维有限元分析模型,并利用螺杆泵水力特性试验数据验证该模型的正确性.
The finite element analysis of oil extraction progressing cavity pump three-dimensional model contains the triple nonlinear problems of geometry,material and contact.Because of the complicated inner surface of PCP and the diversity of loads,the finite element model is difficult to be established and calculated.The analytical method is being improved.For this reason,the GLB120-27type oil extraction PCP model established by SolidWorks has been taken as an example.The Mooney-Rivilin model constant of stator ru...
