侧向气动特性在很大程度上影响着跨坐式单轨车的运行安全性。基于CFD方法对不同侧偏角影响下的某跨坐式单轨列车侧向气动特性进行模拟分析。通过比较分析不同方案下的侧向气动力计算结果及列车周围流场结构,得出随侧偏角的增加跨坐式单轨列车侧向气动力逐渐增大,头车受到的侧向力和侧倾力矩最大,因而侧风对头车的运行安全性影响最大的结论。
Lateral aerodynamic characteristics largely affect the operational safety of the straddle monorail. Based on the CFD method, the lateral aerodynamic characteristics of a straddle monorail train under the influence of different side slip angles are simulated. By comparing the calculation results of lateral aerodynamic forces under different schemes and the flow field structure around the train, the results show that the lateral aerodynamic force of the monorail straddle train gradually increases with the lateral slip angle, and the lateral force and side The largest moment of dumping, so the crosswind of the first car running safety greatest impact conclusion.
