Research on Contact Wire Uplift of Typical High-speed Railway at 300km/h and 350km/h

For analysis of distribution rules on contact wire uplift of high-speed railway, the data of continuous contact wire uplift of typical high-speed railway at the speed of 300km/h and 350km/h was calculated and analyzed. The analysis results show that the contact wire uplift is positively correlated with the speed of the train. The uplift in the span is higher than the uplift at the registration point, besides, the contact wire uplift in the overlap and in the tunnel is relatively high. The inspection data calculation method and analysis results can provide effective data for the analysis and evaluation of the dynamic performance of the catenary, thereby infrastructure manager can more comprehensively grasp the operating status, and provide reasonable guiding proposals for operation and maintenance.
