基于标准GM/RT 2142,采用单一变量法就相关参数如何影响车辆抗倾覆能力进行了定性、定量计算分析。分析表明:电机悬挂方式对机车车辆抗倾覆能力的影响较小;车辆轴重、车体侧面面积、车辆高度H对车辆临界倾覆风速有一定的影响,但改变机车车顶轮廓外形是提高机车车辆抗倾覆能力最有效的方法。 Based on the standard GM / RT 2142, a single variable method was used to qualitatively and quantitatively analyze how the relevant parameters affect the anti-overturning ability of vehicles. The analysis shows that the motor suspension mode has little influence on the anti-overturning capability of rolling stock. Axle load, vehicle body side area and vehicle height H have a certain influence on the critical rollover wind speed. However, The most effective way to resist capsizing.
