摘要
随着各地铁线路长时间的运营,刚性接触网出现了各种类型的故障,并给地铁的实际运营造成了很大的困扰[3-4]。针对刚性接触网常见的接触线脱槽和支撑倾斜两类故障,利用虚拟样机技术,建立弓网故障模型,分析了它们对弓网接触力的影响。基于希尔伯特-黄变换,提取并分析了接触力的故障频率特征。
The rigid catenary appeared various types of failures with the metro line running for a long time, which caused a lot of trou bles to the actual operation of subway. According to the disengagement of contact line and the tilt of rigid suspension, which are two kinds of common failures of rigid catenary, several failure models of pantograph catenary are established by using virtual prototyping technology, and their influence on the contact force of pantograph catenary is analyzed eventually. The fault frequency characteristics of contact force are extracted and analyzed based on Hilbert Huang Transform.
