摘要:
针对高寒动车组转向架积雪问题,基于离散相模型对风雪两相流条件下雪花颗粒的运动特性进行了仿真分析,通过在转向架前后两端加装导流板,抑制转向架前端雪花颗粒的上扬趋势以及减少后端回流进入转向架区域的雪花颗粒的数量,并利用流动场协同原理,对转向架防积雪的导流板装置进行优化.研究结果表明:由于列车运行时产生的列车风在转向架区域形成大量低速涡流,导致雪花颗粒随底部高速气流上扬进入转向架,并在低速涡流附近形成堆积;基于流动场协同原理对导流板进行优化后,改善了转向架周围的流场特性,使得积雪量减少了７３．６％ ,有效地减少了转向架区域的积雪.
Abstract:
In view of snow cover problem at the high-speed train steering frame , based on the discrete phase model , the motion characteristics of snowflake particles under the two-phase flow conditions of wind and snow are simulated and analyzed , and the snow rise at the front end of the snowflake steering frame is reduced by designing the added flow guide plate at both ends of the steering frame．The upward trend of flower particles is restricted and the number of snowflake particles entering the steering frame area by the rear end reflow is reduced．Finally the principle of flow field synergy is introduced and used to solve the incompressible turbulence deflagration area flow field , and optimize the overall optimization of the steering frame anti-snow guide device．The results show that the train wind generated when the train is running forms a large number of low-speed vortex in the steering frame area , which causes snowflake particles to rise into the steering gear with the bottom high-speed air flow and form a build-up near the low-speed vortex．After the addition of the guide plate and the introduction of the flow plate flow field based on the principle of flow field synergy , the flow field characteristics around the steering frame are improved , resulting in a reduction of ７３．６％ of the snow volume and effective reduction of the snow in the steering frame area．
