Influences of air spring models on dynamics performance of railway vehicle

  • 摘要: 建立了空气弹簧等效模型、线性模型与非线性模型,分析了3种模型对车辆直线平稳性和曲线通过安全性的影响。研究结果表明:在计算车辆直线垂向平稳性时,空气弹簧等效模型计算精度较差,而空气弹簧线性模型和非线性模型计算精度较高; 由于空气弹簧线性模型比非线性模型简单,建议在计算直线垂向平稳性时优先采用空气弹簧线性模型; 在计算车辆曲线通过安全性时,空气弹簧非线性模型能反映空气弹簧的充排气特性,计算精度较高; 由于模型自身的局限性,空气弹簧线性模型和等效模型无法反映空气弹簧的充排气特性,计算精度较差,因此,建议在计算曲线通过安全性时采用空气弹簧非线性模型。
