Steering Behaviors of Coupled Bogie with Independent Wheels

摘要: 提出了一种新型的独立轮对转向架方案——独立轮对耦合转向架.理论分析表明,独立轮对耦合转向架不仅在曲线上具有很好的径向调节功能,而且在直线上也具有良好的复位性能,说明独立轮对耦合转向架能解决独立轮对的导向问题.建立了独立轮对耦合转向架的动力学仿真模型,以分析该转向架的动态导向性能.仿真结果与理论分析结果吻合.Abstract: A new design for coupled bogies with Independent wheels was proposed.Theoretical analysis reveals that the bogies have good radial steering ability on a curved track and restoration ability on a tangent track,indicating a prospect to improve the steering performances of ordinary bogies with independent wheels.A dynamic model for the bogies was derived to evaluate the dynamic steering performances,and the simulation results accord with those of theoretical analysis.
