摘　　要：针对一种新型单轴转向架跨座式单轨车辆结构的曲线通过性,文章建立了"车—轮—轨"耦合动力学模型。研究不同曲线路面超高率来分析其对车辆动力学曲线通过性能的影响,通过分析仿真后的工况表数据变化得出满足车辆曲线通过性能最优化的超高率区间参数。研究结果表明:曲线超高率对车辆曲线通过性有着很大的影响;曲线超高率在6%~12%区间内增大,车辆的曲线通过性能变好;但曲线超高率超过12%时,运行阻力加大,轮胎磨耗加重,乘坐舒适性变差。因此在今后单轨列车运行线路建模时曲线超高率建议为10%~12%。Aiming at the curve passing of a new type of single-axle bogie straddle monorail vehicle structure, the ＂vehicle-wheel-rail＂coupling dynamic model is established. The influence of different curves on the performance of vehicle dynamics curve is analyzed. By analyzing the data change of the working condition table after simulation, the range parameters of ultra high rate which can satisfy the optimization of vehicle curve passing performance are obtained. The results show that： the curve super high rate has a great influence on the vehicle curve passing ability, the curve ultra-high rate increases in the range of 6% to 12%, and the curve passing property of the vehicle becomes better, but when the curve ultra-high rate exceeds 12%, the running resistance increases and the tire wear and tear increases. Heavy, curve passing performance becomes worse. Therefore, in the future monorail train running line modeling curve ultrahigh rate suggested is 10% to 12%.
