摘要
输电导线的初始找形是进行后续各种塔线体系结构动力分析的基础和前提.针对输电导线找形在ANSYS上的实现,本文提出了一种节点滑移法,并将该方法用于实例找形分析中,得到的导线的弧垂值和应力值与它们各自的理论值之间的误差很小,在工程允许范围内,证明了用该方法进行导线找形计算的准确性和可行性.本文提出的节点滑移法与实际架线过程近似,克服了常规方法的一些不足,拓展了导线找形这个课题的研究.
Initial form-finding of transmission lines is a prerequisite and basis of subsequent dynamic analysis of various transmission lines. Focusing on how to realizing form-finding of transmission lines in ANSYS, this paper proposes a method named node sliding method which is justified within a case whose results show that the error between the sag and the stress value calculated using the method and their theoretical value meet the relevant engineering requirement. It is proved that using the method to realize form-finding of transmission lines is feasible and accurate. The node sliding method is close to the actual process of framing line. It can o- vercome some shortcomings of the conventional method and expand the study of form-finding.
