唐驳虎:王梦恕院士胡说八道 高铁长期降速浪费惊人

2016-06-28 16:11:15   凤凰新闻客户端

而且,即使是专家,受限于体制身份,很多时候会言不由衷的、被迫讲出许多违心的话,这些年笔者已经见得太多了。

不管什么问题,有没有问题,我们最终都得按事实和科学来说话,对不对?

笔者按媒体报道的原文顺序来逐段批驳。

【高铁提速目前不具备技术条件,“这就像运动员,长时间超负荷运动,肯定活不长!”】

是提速还是达速?高铁降速已经5年了,被很多人当成了理所应当天经地义的事情。谁知从十多年前的筹备期开始,无论车辆还是线路,都是按350时速设计的。而且无论是线路曲线半径还是机车功率,都留了10%-20%的余量。也就是达到了385~420公里。这都是验收试验证明了的。

【根据媒体报道,当高铁创下486.1公里时速纪录的同时,试验列车几乎所有的轴承都要更换。】

胡说八道。

【王梦恕认为,机车速度保持在额定速度的80%是最理想的,“设计时的额定速度为350公里,】

设计时的运营速度的确是350公里,设计者们不会想到余量问题么?成千上万车辆、建设方面专家付出的努力就被你抹杀了么?

【目前没有一个机车的时速跑到350公里,时速310公里的都没有。最快也就跑302公里左右,时速320公里的速度有些司机都不会跑,因为他担心出问题。”】

首先说,高铁是动车组,不是机车。不知道是王的口误还是记者记错。先别说外国,按中国高铁来说,即使在目前,350高铁建成验收试验都是要按385来的。怎么没有?

至于运营部分,现在铁道部/中铁高层命令降速,当然没有了。

“时速310公里的都没有。最快也就跑302公里左右,”废话,运监系统设在了310公里,自然没有了。

“时速320公里的速度有些司机都不会跑,因为他担心出问题。”废话,如果司机谁突破310,运监系统就立刻自动报警,强制降速,回去后司机下岗!不就是制度约束么?你这唬弄谁呢。

【王梦恕说:“中国现在的高铁技术已经是世界领先了,全世界也没有任何一个国家的高铁运行时速是350公里。”】

的确目前没有350.但是欧洲几条新开通的高铁,运行速度达到了320公里、330公里。虽然比不上中国高铁曾经达到的350,但已经超越了你现在的300。而且,350、乃至拟议的俄罗斯用中国技术的400高铁,国外都有在设计和施工。
