麦克斯韦阻尼器模型长期以来被铁路车辆动力学仿真所采用，成为多体动力学软件中的基本力单元。本文的主要目的是考察该模型对铁路横摆减振器阻尼特性和车辆稳定性评估的预测准确性。为了实现这一目标，一个简化的物理阻尼器模型，这是准确的，在同一时间提出了低的计算成本，能够采用在铁路车辆的多体动力学模型，以加快数值模拟。在阻尼器台架试验中进行了适当的验证，并将这两种阻尼器模型的仿真结果与实测数据进行了比较。结果表明，该典型偏航阻尼器的传统麦克斯韦模型不能准确描述其动态特性，而简化的物理模型能准确再现实际阻尼器系统的复杂特性，且计算效率高。将麦克斯韦模型和本文提出的简化物理模型集成到中国高速列车的多体动力学模型中，对与车辆稳定性相关的车辆动力学进行了比较。结果表明，只要在麦克斯韦模型中设置一个合适的动刚度值，麦克斯韦模型就能准确地再现车体失稳现象。在转向架不稳定性仿真中，麦克斯韦模型高估了该典型偏航阻尼器的动态阻尼，导致稳定性计算误差较大。
The Maxwell damper model has been adopted in the simulation of railway vehicle dynamics for a long time and became a basic force element in the multi-body dynamics software. The main purpose of this article is to investigate the predictive accuracy of this model for a railway yaw damper in damping characteristics and vehicle stability assessment. To achieve this objective, a simplified physical damper model was developed for comparisons, which is accurate and at the same time presents low computational costs, being able to be adopted in the multi-body dynamics model of a railway vehicle to speed up the numerical simulations. It was suitably validated in the damper rig test, and simulation results for those two damper models were compared with measured data. Results showed that the traditional Maxwell model of this typical yaw damper cannot accurately describe its dynamic behaviors, while the simplified physical model can accurately reproduce the complex behavior of the actual damper system with a high computational efficiency. Comparisons of vehicle dynamics relevant to vehicle stability were then carried out, by integrating the Maxwell model and the simplified physical model presented in this work into a multi-body dynamics model of a high-speed train in China. It was found that the Maxwell model can reproduce the phenomenon of carbody instability accurately if an appropriate value of the dynamic stiffness is set in the Maxwell model. In the simulation of bogie instability, the Maxwell model overestimates the dynamic damping of this typical yaw damper, and as a result it leads to large errors in stability calculations.
