本文提出了一种分析重型货物列车动力学进行了从数值和实验的角度来看。开发了一种研究重载列车动力学的数值方法;所提出的方法结合了一种新的数值模型，该模型是为整个列车组的纵向动力学设计的，称为TSDyn（TrainSet动力学模拟器），多体代码名为MoNSTram模块化非固定有轨电车动力学模拟器最初是为了分析模块化有轨电车的动力学而开发的，并用于更详细地研究列车段的响应。在线测试已经进行了旨在获取数据的验证的模拟代码和缓冲器的响应的特性。最后通过数值计算分析了列车编组对行车安全的影响。
The paper presents an analysis of heavy freight train dynamics carried out both from a numerical and experimental point of view. A numerical procedure has been developed to investigate the dynamics of heavy freight trains; the proposed methodology combines a new numerical model designed for the longitudinal dynamics of the whole trainset called TSDyn (TrainSet Dynamics simulator) with a multi-body code named MoNSTram (Modular Non-Stationary TRAMcar dynamics simulator) originally developed to analyse the dynamics of modular tramcars and used for a more detailed investigation of the response of a trainset segment. On-line tests have been carried out aiming at acquiring data both for the validation of the simulation code and for the characterisation of buffers’ response. A numerical analysis is eventually presented to show the effect of trainset composition on running safety.
