Abstract

The Sichuan-Tibet railway line, where overhead conductor rail (OCR) system is considered to be utilized in tunnels, has a design speed of up to 200 km/h, which is much higher than conventional OCR lines, whereas literature related to the high speed OCR system is limited. Finite element model of OCR is developed based on absolute nodal coordinate formulation, and a linearization process is applied on the model to reduce computational time. Then influence of key parameters on OCR system when operating at 220 km/h (10% for design margin) is analyzed based on the linearized model. Span length, bending stiffness and linear density are revealed to be sensitive parameters when designing a high speed OCR with better performace. Some special span length configurations which leads to worse performance are pointed out. Then influence of contact wire irregularities is analyzed and it is found that irregularities of specific wavelengths result in worse performance than others. Some suggestions about design and maintenance of OCR system are given in the end of this paper.
