2“身材”更好
采用全新低阻力流线型车头和车体平顺化设计,列车看起来线条更优雅,跑起来也更节能。坐过“和谐号”的朋友都会发现,动车组车顶有个“鼓包”,那其实是受电弓和空调系统。“复兴号”把这个“鼓包”下沉到了车顶下的风道系统中,使列车不仅看起来更美,列车阻力比既有CRH380系列降低7.5%-12.3%,列车在350公里时速下运行,人均百公里能耗下降17%左右。
3“容量”更大
从外面看“复兴号”身材更好了,登车后,旅客还会惊异于空间更大,因为列车高度从3700毫米增高到了4050毫米。虽然断面增加、空间增大的情况下,按时速350公里试验运行,列车运行阻力、人均百公里能耗和车内噪声明显下降,而且有心的乘客还会发现,座位间距更宽敞。
4舒适度更高
“复兴号”空调系统充分考虑减小车外压力波的影响,通过隧道或交会时减小耳部不适感;列车设有多种照明控制模式,可根据旅客需求提供不同的光线环境。当然更值得喜大普奔的是,车厢内实现了WiFi网络全覆盖。当然,这个连接效果如何,还有待乘客们上车检验。
5“警惕性”更高
“复兴号”设置智能化感知系统,建立强大的安全监测系统,全车部署了2500余项监测点,比以往监测点最多的车型还多出约500个,能够对走行部状态、轴承温度、冷却系统温度、制动系统状态、客室环境进行全方位实时监测,采集各种车辆状态信息1500余项,为全方位、多维度故障诊断、维修提供支持。列车出现异常时,可自动报警或预警,并能根据安全策略自动采取限速或停车措施。在车头部和车厢连接处,还增设碰撞吸能装置,在低速运行中出现意外碰撞时,可通过装置变形,提高动车组被动防护能力。
