摘要

本文研究了中低速(LMS)磁悬浮列车在装有铅橡胶支座(LRB)的隔离桥上行驶时的动态响应。在车辆-导轨桥模型中,车辆被模拟为由车体和十个转向架模块组成的 50 自由度模型。带 LRB 的导轨桥采用有限元法建立,导轨与车辆之间通过主动控制的电磁力相互作用。采用非线性弹簧元素模拟 LRB,以反映其滞后性能,并提出了一种快速非线性分析(FNA)方法,以实现 LRB 在车辆载荷作用下的潜在非线性行为。然后,研究了磁悬浮车辆在带 LRB 的隔离桥上运行的动态响应,并与非隔离桥上的动态响应进行了比较。研究了车辆速度和 LRB 隔离程度对耦合系统响应的影响。此外,还讨论了车辆在 LRB 桥上的行驶质量,并全面评估了 LRB 在磁悬浮线路桥梁上的适用性。结果表明,安装 LRB 对车辆-导轨系统的垂直响应影响相对较小,但可以扩大横向响应。耦合系统的横向响应更容易受到隔离度的影响,因此建议 LRB 的隔离度不应超过 2.50,以保证行车舒适性和运行安全性。

Coupled vibration of low-medium-speed maglev vehicle-guideway system on isolated bridge with lead rubber bearings
This paper investigates the dynamic response of low-medium-speed (LMS) maglev vehicle moving on the isolated bridge with lead rubber bearings (LRBs). In the vehicle-guideway bridge model, the vehicle is simulated as a 50-degree-of-freedom model consisting of a car-body and ten bogie modules. The guideway bridge with LRB is established by the finite element method, and the guideway is interacted with the vehicle by the actively controlled electromagnetic forces. The LRB is simulated by the nonlinear spring element for reflecting the hysteretic performance, and a fast nonlinear analysis (FNA) method is proposed to achieve the potential nonlinear behavior of LRB under vehicle load. Then, the dynamic response of maglev vehicle running on the isolated bridge with LRB is investigated and compared to that on the non-isolated bridge. The effect of vehicle speed and LRB isolation degree on the coupled system responses is studied. Furthermore, the driving quality of vehicle on LRB bridge is discussed, and the applicability of LRB to maglev line bridge is thoroughly evaluated. The results show that the installation of LRB exhibits relatively insignificant influence on the vertical response of vehicle-guideway system, while could enlarge the lateral response. The lateral response of coupled system is much more vulnerable to the isolation degree, and it is recommended that the isolation degree of LRB should not exceed 2.50 to guarantee the driving comfort and running safety.

期刊介绍: Advances in Structural Engineering was established in 1997 and has become one of the major peer-reviewed journals in the field of structural engineering. To better fulfil the mission of the journal, we have recently decided to launch two new features for the journal: (a) invited review papers providing an in-depth exposition of a topic of significant current interest; (b) short papers reporting truly new technologies in structural engineering.
