摘要
针对C_(0)-C_(0)米轨内燃机车建立动力学模型,分析了多种直线和曲线工况下机车平稳性和运行品质。结果表明:随着运行速度的增加,机车横向平稳性和加速度最大值呈上升趋势,指标在不同测量位置由大到小依次为前司机室、后司机室、车体中心;对于曲线工况,机车横向平稳性最大值逐渐增加,司机室大于车体中心,而横向加速度最大值在曲线半径为130m、800m、1200m时分别呈现线性增长、双线性增长和先降低后增长的趋势。
The dynamic model of C_(0)-C_(0)meter gauge diesel locomotive was established,and the locomotive ride index and running quality were analyzed in straight and curve line.The results show that the maximum value of lateral ride index and acceleration of locomotive maintain an upward trend with the increase of running speed and the index values in different measurement positions are in the order of front cab,rear cab and carbody center.For curve negotiating case,the maximum value of locomotive lateral ride index increases gradually and index is larger at the cab than at carbody center.The maximum value of lateral acceleration increases linearly,bilinear and decreases first and then increases when the curve radius is 130m,800m and 1200m,respectively.
