When high-speed trains operate in cold regions, ice and snow can accumulate on the surface of the bogies after experiencing rainy and snowy weather, which can affect the dynamic performance of the train's suspension components and braking system, thereby compromising safety. The formation of ice and snow accumulation is caused by the train passing over snow-covered roads or in snowy environments. Under the influence of the train's wind, snow particles follow the airflow into the bogie area. Due to the presence of many low-speed and vortex areas in the bogie, snow particles cannot be discharged and have adhesiveness, which can easily adhere to the surface of the bogie and form snow accumulation. Under the action of the heating components of the bogie such as motors and gearboxes, snow particles will melt into liquid water, which not only increases the ability to capture snow particles but also easily condenses into ice in low-temperature environments. Therefore, to study the ice and snow accumulation process in the bogie area and propose corresponding prevention and control measures, this paper establishes a simulation model of ice and snow accumulation and prevention, and studies the ice and snow accumulation under different conditions and the effects of preventing ice and snow. The main research content and conclusions are as follows
