Pantograph is a critical component of the high-speed train. It collects power through contact with catenary, which significantly affects the running safety of the train. Pantograph with double collector strips is one common type. The aerodynamic performance of the collector strips may affect the current collection of the pantograph. In this study, the aerodynamic performance of the pantograph with double strips is investigated. The numerical results are consistent with the experimental ones. The error in the aerodynamic drag force of the pantograph between numerical and experimental results is less than 5%. Three different conditions of the strips are studied, including the front strip, the rear strip, and the double strips. Results show that the presence of the front strip will affect the lift force of the rear strip, and reduce the resistance of the rear strip under the opening condition. Meanwhile, the rear strip has few effects on the front strip under the opening operation condition. The law of the resistance for the interaction between two strips under the closing condition is similar to the opening one.
