Nowadays， various track structures have been applied in Chinese high-speed railway， which obviously causes the adaptability problems for electric multiple unit (EMU) running on the tracks. It is significant to carry out the investigation of track adaptability. Therefore， based on the theory of vehicle-track coupled dynamics， the method of adaptability design for high-speed EMU running on the tracks is preliminarily discussed in this paper. By regarding the high-speed EMU as the design object， a method of track adaptability design is presented， which can supply a new idea and reference for Chinese high-speed EMU. Lastly， the application of this method is introduced in the dynamic performance design of Chinese standard EMU.
