摘要
将应力-应变曲线与导线相结合,从相关的导线分层力学模型出发,对其进行抗拉、疲劳问题的综合分析计算。计算结果与实际导线破坏情况较为吻合,能较好的应用在导线机械性能的验算中,为导线的参数选择,结构优化提供数值分析方法。
In combination with the stress-strain curve the integrated calculations of the tensility and fatigue of the conductor are carried out based on its the stratified mechanical model in this paper. The results are in agreement with the rupture condition of the wire under stress, and thus the calculation method can evaluate mechanical properties of the conductor and offer data for choosing its parameters and optimizing its structure.
