Validation and Analysis on Numerical Response of Super‐High‐Speed Railway Pantograph‐Catenary Interaction Based on Experimental Test

The numerical tools can be used to facilitate the design of the railway pantograph‐catenary system. The validation of the current numerical results is mostly performed at a speed slower than 350 km/h. This paper aims at the validation and analysis of the numerical results at a super‐high‐speed. The catenary model is constructed based on a nonlinear finite element approach employing the absolute nodal coordinate formulation. A multibody dynamics model is adopted to represent the pantograph. The measurement data are collected by an inspection vehicle equipped with an instrumented pantograph operating at 378 km/h in Chengdu‐Chongqing high‐speed line. Comparing the numerical simulation and the field test shows that the present pantograph‐catenary model can provide reliable numerical results at 378 km/h. The numerical analysis of pantograph‐catenary interaction at super‐high‐speed shows that the trailing pantograph performance does not comply with the assessment standard at 378 km/h. The adjustment of double‐pantograph interval and messenger wire tension can effectively improve the trailing pantograph performance.
