摘要:
基于建立的动力学仿真模型，采用车线动力学分析方法探讨了速度为400km/h、450km/h和500km/h轮轨高速铁路的主要线型指标，确定了满足安全性、舒适性和轮轨动力性能条件下，平面曲线半径以及超高与行车速度的匹配关系。结果表明：（1）行车速度为400km/h时，最小曲线半径一般情况可取8500m，困难情况取7500m；450km/h时，最小曲线半径一般情况可取11500m，困难情况取9500m；500km/h时，最小曲线半径困难情况取12000m；（2）400km/h与450km/h速度条件下，越接近均衡超高，行车的安全性指标与横向舒适度评价结果越好，适当的欠超高情况下，行车的轮轨动力响应评价结果更优。
Abstract:
Based on the dynamic simulation model established in this paper，vehicle-track dynamic analysis was employed to investigate the main alignment indicators of wheel-rail high-speed railways with speeds of 400 km/h，450 km/h， and 500 km/h. The matching relationship between the planar curve radius and super-elevation under the conditions of safety，comfort，and wheel-rail dynamic performance was determined. The results show that：（1）When the running speed is 400 km/h，the minimum curve radius can be 8 500 m under general conditions，and 7 500 m under difficult conditions；when the running speed is 450 km/h，the minimum curve radius can be 1 1500 m under general conditions，and 9 500 m under difficult conditions；and when the running speed is 500 km/h，the minimum curve radius is 12 000 m under difficult conditions. （2）When the running speed is 400 km/h or 450 km/h，the closer the actual superelevation is to the equilibrium value，the better the safety index and lateral comfort evaluation results are. Under the appropriate deficient superelevation，the evaluation results of wheel-rail dynamic response are superior during train operation.
