高原机车悬挂方案对车辆振动特性的影响
|
摘要
针对青藏铁路冻土带路基下沉问题,为了实现高原机车转向架低动力作用,基于车辆多体系统动力学理论,建立了两种不同悬挂方案的高原机车动力学模型,研究了不同一、二系悬挂刚度比μ对车体、构架以及轮轨垂向振动的影响。发现一、二系悬挂刚度比在0.5~3范围内变化时,轮轨垂向力和构架垂向振动加速度增大了11.24%和12.2%,车体平稳性指标和垂向加速度分别减小了11.3%和15%,并分析了高原线路上两种悬挂方案机车动力学特性。计算结果表明,选择刚度较大的二系悬挂,虽然一定程度上恶化车体平稳性指标,但较小的一系刚度在中低速范围内,能够降低由轨道不平顺引起轮轨垂向冲击,显著抑制了对轨下部分损伤较大的低频振动,减小运行过程中机车对轨下部分的损害。
