FXD3-J型动车组动力车总体技术研究

Research on General Scheme Technology of FXD3-J EMUs Car

为提升我国普速铁路旅客舒适性和客运专线运输能力而开发了CR200J型动力集中动车组。该型动车组采用的动力车基于互联、互通、互控等原则进行设计,通过试验和考核后最终定型为FXD1-J和FXD3-J。围绕FXD3-J型动力车的定位与功能,阐明了设计原则,对动力车顶层设计指标进行了研究,重点论述了动力车限界、轴重、牵引性能、设备布置、速度等级等总体技术指标及设备布置。实际应用表明,FXD3-J型动车组动力车满足设计要求。

The CR200J power concentrated EMUs are power concentrated EMUs,developed to enhance the comfort of China’s railway general speed train passengers and the transportation capacity of passenger dedicated lines.The power car was designed based on the principles of interconnection,interoperability,and mutual control.After testing and assessment,it was finalized as FXD1-J and FXD3-J.Based on the positioning and function of the FXD3-j power car,this paper expounded the design principle,studied the design index of the top-level of the power car,and focused on the overall technical indicators such as the limit,axle weight,traction performance,equipment layout,and speed grade of the power car.The practical application showed that the FXD3-j EMUs meet the design requirements.
