摘要

针对提出的一种覆冰四分裂导线智能除冰方法,采用ABAQUS有限元软件建立覆冰四分裂导线及其除冰装置的有限元模型,实现除冰过程的数值模拟方法。通过数值模拟研究,验证智能除冰方法的可行性。覆冰破坏采用拉伸破坏强度理论,利用ABAQUS的用户材料子程序VUMAT定义覆冰的本构关系和破坏准则,实现破坏单元的删除。通过除冰装置不同张开位移和安装个数以及不同覆冰厚度下除冰效果的模拟研究,为智能除冰装置的设计提供参考。

Abstract

Numerical model of an iced quad-bundled conductor line with new intelligent de-icing equipments is set up by means of ABAQUS software, and simulation method of the de-icing process is numerically carried out. The feasibility of the intelligent de-icing method is verified based on the numerical simulation. Tension failure criterion is employed in the simulation of the failure of the ice, and the user material subroutine VUMAT of ABAQUS software is developed to introduce the constitutive relation of the ice and the deletion of the broken ice elements. Several de-icing scenarios are numerically studied with the variables including opening displacement of the de-icing equipment, the number of installed de-icing equipments on the line and the thickness of the ice covered on the conductors. The obtained numerical results provide a reference for the design and realization of the intelligent de-icing equipment.
