【 摘 要 】

Conducting the study on the comfort of high-speed train drivers in a windy environment, this paper based on the logical sequence of "train aerodynamic characteristics - vehicle dynamic response - human biomechanical properties - human body comfort evaluation". Taking the domestic CRH3 high-speed train as the research object. Firstly, the aerodynamic loads acting on the car bodies of the train under different wind speeds and different vehicle speeds were calculated. Then considering the effect of the wheel-rail adhesion and the irregularity of the track line, establish a vibration transfer model of 'rail - wheelset - bogie - carriage - seat', the aerodynamic loads are loaded onto the train to calculate vehicle dynamics and train vibration response under different operating conditions, the vibration characteristics of carriages and seats are obtained. Subsequently, the seat-human vibration transfer model were established and the seat vibration response was introduced into the human dynamics model to calculate the vibration response of different body parts of the driver under different operating conditions. And on the basis which are mentioned above, we summarized the influence rule of wind speed and train speed on human vibration response, From the human body's own point of view, the main factors affecting comfort and the mechanism of action were analyzed. Finally, the comfort standard was integrated to evaluate the comfort of the driver.
