摘要
目前,200km/h的交流传动动车组已经运行在沪杭、沪宁既有线上。未来350km/h的交流传动动车组将在京津、沪宁城际铁路和京沪高速铁路上运行。高速动车组具有重量轻、粘着利用好、起动加速度快等特点。以CRH2型4动4拖8节编组为例,介绍交流传动动车组牵引加速度、牵引力、制动力和制动距离等的计算,以及在故障情况下的运行特点。
Ourrently, AC transmitted motor trains at the speed of 200 km/h have been running on Shanghai--Hanghou and Shanghai--Nanjing lines. In the near future, the high-speed AC transmitted motor railway trains of 350 km/h will be running on more intercity lines, like Beijing--Tianjin, Shanghai--Nanjing and Beijing--Shanghai line, etc., because this motor train features light-weight, good adhesion, quick-start acceleration and so on. This paper takes Type CRH2--total 8-set:4 motor cars and 4 dragging cars --as an example, introduces the calculations of traction acceleration, traction force, brake force and brake distance of AC transmitted motor trains, and especially introduces the operational characteristics under the failure conditions.
