气动力学特性在很大程度上影响着跨坐式单轨车的性能。基于数值模拟计算方法对某跨坐式单轨车原车型、新车型的气动力学特性进行模拟分析,计算得出原车型、新车型的风阻系数;并结合两种车型的外部流场结构进行了比较分析,从而验证流线型的新车造型更为合理。 Aerodynamic characteristics largely affect the performance of the straddle monorail. Based on the numerical simulation method, the aerodynamic characteristics of the original model and the new model of a monorail monorail were simulated and analyzed, and the drag coefficients of the original model and the new model were calculated. The external flow field structure of the two models was compared Analysis, to verify streamlined new car styling more reasonable.
