Study on the wind-induced security for 350km/h high-speed trains

The aerodynamics and multi-body system dynamics are combined to study systematically the characteristics of wind-induced security for high-speed trains with the speed of 350km/h.It first establishes the aerodynamic model of the high-speed train for the head car,the middle car and the tail car,and analyzes the characteristics of aerodynamic loads of high-speed train under different side-wind velocities(including different wind speeds and different wind angles).Then it establishes the multi-body system dynamic model of the high-speed train with the trailer car,the motor car and the trailer car,on which the aerodynamic loads are dealt with as external loads to study the operation safety and operation attitude of 350km/h high-speed trains,which provides a reference for the safe operation of high-speed trains with the speed of 350km/h under side-wind.
