Abstract
In this paper, the fluid calculation software CFD and the dynamic model software SIMPACK are used to study the influence of strong crosswind on the aerodynamic pressure, aerodynamic load and operation safety of EMUs on different road conditions. The influence rule of strong crosswind on the aerodynamic pressure and aerodynamic load of the train under different road conditions was obtained. Then the relationship between aerodynamic load and yaw angle and the critical wind speed curve of EMUs under different running conditions were obtained.
