摘要: 从轮轨蠕滑力出发, 研究了纵向耦合独立旋转车轮转向架的导向机理, 通过建立独立旋转车轮转向架整车动力学模型, 基于数值仿真方法, 分析比较了采用纵向耦合独立旋转车轮转向架、横向耦合独立旋转车轮转向架与全独立旋转车轮转向架车辆的导向性能。计算结果表明: 纵向耦合独立旋转车轮轮对具备直线上的对中性能和曲线上的导向性能; 在曲线通过时, 与横向耦合独立旋转车轮转向架相比, 同样具有足够的轮轨纵向蠕滑力; 导向轮对的冲角较小, 仅为全独立旋转车轮转向架的1/2;轮轨间磨耗也明显减小, 磨耗指数约为全独立旋转车轮转向架的1/3;其他曲线通过性能指标也明显优于全独立旋转车轮转向架。可见, 纵向耦合独立旋转车轮转向架具有较好的导向能力。Abstract: From the angle of creep forces between wheels and rails, the guiding mechanism of longitudinal coupling bogie with independently rotating wheels (IRW) was studied. Full vehicle dynamics models of different IRW bogies were built, and the guiding performances of longitudinal coupling IRW bogie, lateral coupling IRW bogie and full IRW bogie were investigated and compared through numerical simulation. Calculation result shows that the longitudinal coupling IRW bogie has good centering ability on straight line and good guiding on curve. During curve negotiation, longitudinal coupling IRW bogie has enough wheel/rail longitudinal creep force compared with lateral coupling IRW bogie. The attack angle of leading wheelset is smaller and only half of the value of full IRW bogie. Wheel/rail wear significantly reduces, and is about one-third of the value of full IRW bogie. Other curving performance indexes are also superior to full IRW bogie. It can be seen that longitudinal coupling IRW bogie has good guiding capability.
