Study on Numerical Optimization of Cross-sectional Panhead Shape for High-Speed Train

Abstract

A new design technique for panheads of pantographs used on high-speed trains was proposed to take much of the load off wind tunnel experiments on the development of the pantograph. The technique with emphasis on reduction of computational costs determines the cross-sectional panhead shape numerically, which balances low-level aeroacoustic noise property with stable lift force characteristics. An examplary panhead designed by this technique was examined by wind tunnel experiments. The test results successfully demonstrated the capabilities of the method.
