摘　　要：列车动力学及列车能耗分析对重载运输的安全性及经济性有着重要意义。在列车纵向动力学的基础上进行列车能耗、能量分析能够更加清楚地认识列车能耗、能量的组成成分，在保证列车运行安全性、降低列车纵向力的前提下提出更加有效、更加合理的节能措施。为进行重载列车纵向动力学及列车能量、能耗研究，开发了综合考虑能耗分析的纵向动力学仿真软件，并利用该软件对组合列车进行了算例分析。Analysis of train dynamics and energy consumption has significant safety and economic meaning on heavy haul transport. Analysis of train energy and consumption based on longitudinal train dynamics（LTD） analysis can get a better understanding of the consists and components of train energy and consumption. This approach can be help to make heavy haul trains run safely, mitigate longi- tudinal forces and reach more effective and reasonable energy conservation policies. In order to perform studies regarding heavy haul train dynamics and energy, energy consumption, a simulation package was developed. A case study of longitudinal train dynamics, train energy and energy consumption was presented in this paper with the help of the newly developed tool.
