“真人BBwBBWBBw”冠军中国·青春接真人BBwBBWBBw力|高铁“风火轮”如何炼成?

  地表真人BBwBBWBBw最快高铁如何炼成?少不了它——真人BBwBBWBBw齿轮箱!齿轮箱相当于高铁的“膝盖”,能直接决定高铁跑多快。青青智造家金思勤和同事们研发出了全国首款具有完全自主知识产权的高铁列车齿轮传动系统,你坐的复兴号列车上就有同款“风火轮”。

  12月3日,“冠军中国青春接力”网络主题活动暨我比任何时候更懂你(第四季)系列短视频之《高铁“风火轮”如何炼成》上线。在本集短视频中,青青智造家、中国中车资深技术专家金思勤,向大家介绍了他们研发的全国首款具有完全自主知识产权的高铁列车齿轮传动系统,揭示了高铁贴地飞行的“奥秘”。

  高铁从南到北要跨越-40℃至45℃的温差,齿轮箱就要成为适应各种环境的六边形战士。金思勤和同事们翻遍了各种轴承、润滑书籍,反复讨论,终于用“温控技术”解决了这一难题。

  为了模拟设备装车后的真实环境,他们还自主研发了全工况模拟试验台,风沙雨雪轮番上阵……夏天去最热的地方,冬天去最冷的地方,试跑测试60万公里以上,“风火轮”才能过关上岗营业。

  就这样,历经上万次试验,他们打造出了首款“中国制造”品牌的高铁列车齿轮传动系统。目前,随着CR450动车组样车的加快研发,金思勤和同事们研制的更高等级的齿轮箱也将投用,助力高铁时速提升至400公里,成为地表最快高铁。

  为深入学习宣传贯彻党的二十届三中全会精神,11月8日起,由中共江苏省委网信办出品、现代快报+制作、中国互联网发展基金会中国正能量网络传播专项基金资助支持的“冠军中国青春接力”网络主题活动暨我比任何时候更懂你(第四季)系列短视频高燃上线。该网络主题活动以高质量发展推进中国式现代化为主线,通过全国24座城市30位青青智造家的沉浸式、场景化讲述,探寻各地因地制宜发展新质生产力的改革创新实践,用AI技术打造的“3D未来之眼”带网友穿越到美好未来。
