9 Siulation of Train Dynaics in Subway Syste M. A. Sandidzadeh, Assistant Professor, S.Safarkhani Tabrizi, M.Sc A. Mirabadi, Assistant Professor Departent of Railway Engineering, Iran Uniersity of Science and Technology, Tehran, Iran E-ail : sandidzadeh@iust.ac.ir ABSTRACT Nowadays coputer technology proides different ways to check technical and econoical study of DC traction supply systes projects. It is quite possible to siulate the rolling stock transportation based on operation progra, also oltage and current calculation and deterines the rectifiers and inerters outputs in eery oent and position and also it is possible to check the rectifier substation proposed positions. The estiated passenger nuber, operation progra and passenger cofort are necessary paraeters in rolling stock selection. It is possible to deterine rectifier output in noral and one transforer rectifier unit out of serice condition. As well calculation proides the inforation of energy consuption and rail oltage regarding the earth. Rolling stock data is needed for calculation and siulation. As an exaple it is necessary to know otor specification at otoring and braking condition, its weight and also track data such as gradient, cure and axiu speed. All contact line, current returning circuit, substation place and operation progra data ust be defined. The first step to siulate traction supply network is siulating the train dynaic oeent in order to specify the position, speed, acceleration and rolling stock power consuption. Therefore this topic was chosen for the present research. In this paper the dynaic train dynaics was taken into account. The train dynaics graph was presented as a key cure in deterination of the nuber of existent trains in return lines and by the siulation process, the oent rates of echanical paraeters such as the location, the consuption rate of trains in each point of the line and the oent elocity of the return trains are presented. Keywords: Dynaic siulation, train oeent, train graph
