接触网覆冰脱冰动力响应的有限元仿真
Finite ele ment simulation of dynamic response of the catenary icing and de -icing
摘要
Abstract
The influence of mechanical impact of extra loading source on catenary was researched in this paper. At first,the static model of catenary simple chain suspension was built,based on which the catenary icing model was obtained.Then dynamics analysis was carried out for the model,and the inherent frequency of catenary un-der icing condition was calculated though modal analysis,harmonic response analysis and transient dynamics a-nalysis.Best loading frequency scope of de -icing was supposed to be much higher than 1.5 kHz.The best loading method was obtained by changing the way the loading increases.Finally,the method was applied to ob-taining the best de -icing solution under general icing conditions by comprehensively considering different load-ing points,the frequency of loading and the way the loading increases.关键词
