覆冰导线的空气动力参数是导线舞动的关键因素.由于覆冰形状的多样性,风洞试验研究代价巨大,仅靠风洞试验提供覆冰导线的空气动力参数是不实际的,因此有必要采用数值模拟的方法.提出了基于面元法的覆冰导线空气动力参数的数值模拟方法,采用有粘性的绕流模型,编制计算程序对覆冰单导线随攻角变化的空气动力参数进行了数值模拟计算.该程序系统简单易用,能快速得到结果.通过比较,所得数值模拟结果与试验结果基本一致,一定程度上反映了覆冰单导线气动力的规律.该方法是一种实用、快速、有效的数值解法,为覆冰导线舞动计算与仿真的深入研究提供了一种有效的途径.
The aerodynamic parameters of the iced conductor are the key factors in the galloping of the conductor.Due to the diversity of icing shapes, wind tunnel testing is costly and it is not practical to provide the aerodynamic parameters of the icing conductor solely by wind tunnel tests, so it is necessary The method of numerical simulation is proposed.The numerical simulation method for the aerodynamic parameters of the icing conductor based on the surface element method is presented. The viscous flow around the flow model is used to calculate the aerodynamic parameters Numerical simulation results show that the system is simple and easy to use, and can get the result quickly.Compared with the experimental results, the simulation results of the ice-covered single-wire are consistent with the experimental results to a certain extent.This method is a practical, The rapid and effective numerical solution provides an effective way for further research on the calculation and simulation of icing conductor galloping.
