摘要
应用 2 9个自由度的车辆动力学模型研究直线轨道上较高速度货车脱轨的问题 ,文中探讨了通过改变转向架悬挂刚度来提高直线线路上较高速度货车脱轨稳定性的可能性 。
The derailment of freight cars with fairly high speed on straight line is researched with the vehicle dynamic model of 29 degrees of freedom.In the paper,the possibility to improve the derailment stability of freight cars with fairly high speed on straight line is discussed by changing the suspension stiffness of bogie.The bifurcated graph of hunting motion of wheelsets is obtained through calculation.
