摘要

本文系统研究了车桥耦合动力系统的分析方法。随着铁路技术的发展,车桥耦合动力分析日臻成熟, 此类研究对评判桥梁设计方案、确保列车运行的安全性与平稳性具有重要意义。车桥耦合动力研 究中考虑轨道不平顺、结构变形、风荷载、撞击荷载、结构损伤、基础冲刷和地震等因素的影响, 其研究方法主要包括解析法、数值模拟法以及试验研究法三类。本文的车辆子系统模型以刚体动 力学方法建立,桥梁子系统模型以有限元方法建立,竖向与横向轮轨关系分别以轮轨密贴假定和 Kalker 线性蠕滑理论定义。车桥耦合动力方程以全过程迭代法求解。算例讨论了CRH380BL 高速 列车通过我国标准设计桥梁的动力响应,计算了车速200~400 km·h-1 范围内车辆与桥梁子系统的 动力响应,并分析了振动发生的机理。
