复兴号将大批量生产 和谐号将逐步退出

2017-06-27 15:49:00   澎湃

原标题:复兴号会大批量生产:设计寿命提高50%,所有车型能连挂

中国标准动车组“复兴号”6月26日实现了上海至北京的双向首发。

6月26日,上海铁路局车辆处副处长叶丹告诉澎湃新闻(www.thepaper.cn)记者,今后“复兴号”会得到大批量生产。现有的“和谐号”动车组到现在服役已有10年,设计寿命是20年,预计将逐步随着设计寿命的到达而退出。从6月26日开始到30日,上海铁路局方面将每天发出一对“复兴号”动车组列车,具体为:G124次从上海虹桥到北京南,G155次从北京南回到上海虹桥,北京铁路局方面也有相应发车。到7月1日后,上海铁路局方面将准备上线4组“复兴号”动车组,每天上线,2组2组分别重连,每天开2对。

从设计上来讲,“复兴号”目前保持持续运行速度350公里/小时。叶丹表示,“复兴号”在每小时300公里到400公里区间内都能跑,最高速度能跑到420公里/小时,但因受制于很多因素,实际不跑这个速度。

澎湃新闻记者6月26日登上了从上海虹桥站发往北京的G124次列车,进行全程直播。叶丹在车上为澎湃新闻记者详细介绍了“复兴号”的性能优势和技术特点。

能耗节约17%,设计寿命提高50%

在牵引性能方面,据叶丹介绍,“复兴号”的每节车厢拥有2个转向架,转向架完全国产化。   

在此基础上,牵引功率较之原来的“和谐号”动车组功率增加。启动性能,包括在高速度运行下的加速度更高,即车辆从静止状态加速到200公里/小时的速度,启动加速度比原来提高5.4%,同时,在持续350公里/小时速度运行的保持加速度比原来增加了42%。   

此外,叶丹透露,“复兴号”的外型设计有更好的评测性,在运行过程中风阻很小。具体而言,通过仿真计算,“复兴号”的阻力比之前的动车组低11%。也正是因为通过阻力的下降,“复兴号”动车组的整个能耗较之前的动车组节约了17%。
同时,“复兴号”的设计寿命也比以往大大增加。据悉,目前“复兴号”的设计寿命是30年,而以往动车组的设计寿命都是20年,直接提高了50%。 

载客量多20人,未来可实时了解所有座位的车票售卖情况 

叶丹介绍,与“和谐号”动车组相比,“复兴号”的载客量更多。以前“和谐号”动车组是556人定员,“复兴号”上则可坐576人,多了20人。具体多出的座位分别为,2、3车各多5个座位,6、7车各多5个座位。    值得注意的是,目前“复兴号”很快就要开通坐席信息显示功能。“我们的车经过和12306的客票系统进行联网之后,就能够看到座位已经卖掉的情况、没有卖掉的情况、预售情况和下一个站可能已经卖掉了的情况,这些都能在坐席电子信息系统显示出来。”
