关于车辆侧倾稳定性计算法的分析

Analysis on Vehicle Roll Stability Calculations

对应标准GB 28373-2012《N和O类罐式车辆侧倾稳定性》建立了较为详细的等效弹簧模型、侧倾时悬挂质量重力引起的侧倾力矩模型、侧倾平面内带悬架汽车准静态侧翻模型,并推导了计算过程。通过易理解的受力分析方程推理了此标准各公式的来源,以熟悉和加深对此标准的理解,最后对此标准的实施执行和理解上提出了两点疑惑和见解。

On the basis of automobile theory, corresponds to the standard GB 28373-2012 Tank Vehicles of Categories N and O With Regard Rollover Stability, equivalent spring model and sprung mass roll moment model were established when the vehicle roll, and vehicle with suspension quasi static rollover model. Through easy to understand stress analysis equations, the calculation process was derived, and the source of every formula in the standard was inferences in order to become familiar and deepen the understanding of this standard. Finally, two doubts and insights on implementation and understanding of the standard were raised.
