CheGou buffering device is the car and motorcycle and the connection between the important parts of vehicles. It besides even hang car traffic outside, still have to keep a certain distance between vehicles, vehicle longitudinal force between the impact between vehicles, etc. CheGou buffer in longitudinal force under certain elastic deformation, and can train vehicles between constraints, therefore, is called the relative displacement of elastic. Vehicles, This method of using Simulink diagram train longitudinal force analysis. In the use of Simulink, we must grasp look-up table, manual switching, output port, multiplication, gain, peace, integrator function module, and the use of oscilloscope, skillfully use graphics, adjust the waveform parameter required size, records of experimental data, etc. Make full use of Matlab and Simulink same data, conduct necessary data processing. Matlab for import data, to grasp the simple calculation, complete data calculation and order statistics. In the simulation of CheGou cushioning aspect, this paper will put 1M1T emu train 2M1T movement of body into the working conditions, braking traction and line working three types of three conditions respectively, the parameters of concrete is analyzed and discussed. Because CheGou buffer with elastic properties, damping and absorb the impact energy of the part. Therefore, this paper will to rigidity and damping coefficient K C are discussed. One of the research on rigidity coefficient K, and divided into fixed rigidity without equivalent friction and variable stiffness with equivalent friction two kinds of circumstances, discuss three characteristics of buffer longitudinal impact. For vehicle braking traction condition, operating conditions, these three conditions with an inert do sport forms, the paper also carries on the simulation analysis respectively. Under the same conditions, the characteristics of three kinds of comparison, showing the speed, travel and buffer parameters such as different CheGou force. And to train for 1M1T, 2M1T discuss various compositions, analyzes the characteristics of different compositions and longitudinal force change.

此次试验有效采集了列车吸能系统的变形次序、防爬车、防脱轨性能等重要数据，成功验证了由中车长客自主研发的高速动车组碰撞吸能系统的安全有效性，标志着我国轨道客车被动安全技术研究达到世界领先水平。

1、动车组这个概念是将列车的动力单元由一个变为多个，像动力集中式动车神舟号，两端为机车中间为无动力的车厢，这样启动需要的牵引力就分散开不需要较大的启动力矩，列车整体制动反应时间也较普通的列车短，车厢间采用密接车钩减小车厢间的空隙，运行更稳定。

2、现在铁路上运行的动车组多为电动分散式动车，也就是一组车有好几个动力单元，将车列分为好几个不同的动力结构进行组合，像CRH2A型 采用的是四节动车四节拖车八节编组，从一端驾驶车到另一端驾驶车依次是 控制端拖车，动车，动车，拖车，拖车，动车，动车，控制端

3、动力安装在动车转向架上，一个转向架两个轮对，每个轮对由一台电机驱动，一节动车有两套这种动力转向架，也就是四个电动机做驱动力，整车有十六个驱动轮对，这样做的好处相比传统电力机车牵引的列车（6个电动机驱动，co-co模式）。

动力单元多，平均每个动力单元承担的驱动力或者是推进功率要比传统机车低很多，相对节省电力，车组启动时由一端驾驶车下达指令，通过电力统一启动分布在各车厢上的电动机产生推力，整车启动时间短，加速快，制动性能方面因为采用电空统一指令，驾驶端拉下制动手柄整车同时制动，动车组的制动距离就相对较短。

还有一个不同之处在于，传统的机车因为需要较大启动力矩所以轴重较大，机车自重一般在100吨左右，而动车因为整体推进不需要这么大的启动力矩，所以轴重轻，这样整体车组的重量就比较小，有利于提高运行速度，也有利于长时间高速行驶，通常动车重心较普通列车低，使动车获得更好的高速稳定性能。

7、另外，动车可以根据需要进行不同的编组，如16节长编组的CRH2B型动车，整车为八动八拖，还有CRH2C型为300公里时速型，采用六动两拖。动车的轻量化对于铁轨的载重要求较轻，对于轨道的摩擦损耗小，便于延长线路寿命和维护保养。另外动车组的运行采用高速控制系统，由中央电脑运行指令，便于高密度发车，提高线路使用效率，增大运能
