摘要:
由于过度卸载将降低轮轨粘着利用效率,因此确定何时应停止卸载非常重要。基于轮轨粘着特性及轮轨运动模型,通过分析空转/ 滑行卸载保护时粘着再恢复过程中轮对加速度和牵引力的变化规律,推导了停止空转/ 滑行卸载的最佳时刻以及最佳时刻的判断方法。试验结果表明,相对传统的空转/ 滑行卸载方法,新算法能够提高50% 以上的粘着利用。
Abstract:
Because over deloading would reduce wheel-rail adhesion utilization efficiency, it was important to determine the critical time when deloadding should be stopped. Based on wheel-rail adhesion characteristics and the dynamic model of wheel movement, this paper analyzed the variation of both wheel acceleration and vehicle traction force during the deloading and re-adhesion process, derived the optimal time for stopping slip/slide deloadding and developed the procedure for obtaining the optimal time. Experimental results show that, compared to conventional deloading schemes for restraining slip/slide, the proposed method can improve adhesion utilization up to 50%.
