摘要
运用轮轨关系,建立高速列车—板式轨道—桥梁系统空间耦合动力学模型。运用列车—线路—桥梁动力学仿真通用软件TTBSIM,分析高速列车以不同速度通过桥梁时,机车车辆、板式轨道及桥梁的动力特性。结果表明,桥上板式轨道能够保证行车的安全性、舒适性和桥梁结构的安全性。
Based on wheel/rail interaction, a coupling dynamics model of high-speed train, slab track and bridge is established. Using the general simulation program TTBSIM for dynamics simulation of train, track and bridge, the dynamic performances of train, slab track and bridge are analyzed when the high-speed train passes through the bridge with different speed. The results show that the slab track on bridge can assure the safety of train operation, ride comfort and the safety of bridge structure.
