西班牙官员赴华考察高铁:希望亲眼见证中国列车制造和技术创新
Huan Qiu Shi Bao· 2025-12-11 22:48
【环球时报特约记者 唐陆一】"为补充西班牙国家铁路公司的高铁运力,西班牙交通大臣奥斯卡·普恩特 前往中国考察,中国公司成为西班牙供应列车的潜在合作对象。"西班牙《国家报》10日如是报道。西 班牙埃菲社称,普恩特11日开启为期3天的丰富访华行程,将在合肥、北京、长春等多个城市深入考 察,"此行旨在深化与中国铁路行业及新能源领域企业的交流合作"。 西班牙交通部表示,普恩特希望"亲眼见证中国列车制造的实际情况"以及该国在全球领先的高铁系统中 的技术创新。 西班牙政府正迫切寻求引入新的高铁列车,以应对国内日益增长的出行需求。西班牙《经济学家报》10 日分析称,普恩特此次访华,正值西班牙国家铁路公司筹备其史上规模最大的一次车队更新,该公司不 仅需要更换老旧列车,还需配合铁路服务扩张需求。据《国家报》报道,为加强高铁与中途距离列车服 务,西班牙国家铁路公司希望在2026年年初启动两项合同招标工作,尽快引入新列车。此前,因新型列 车故障,马德里至巴塞罗那的高铁线路一度陷入"无车可用"困境。此外,西班牙铁路基础设施管理公司 也计划对该国铁路网进行改造,将最高运营时速提升至350公里,这也要求西班牙国家铁路公司更新现 有列车装 ...
CR450研发核心工程师团队接受《环球时报》专访:“全球最快高铁”如何炼成
Huan Qiu Shi Bao· 2025-12-04 22:51
前期试验期间,它一举跑出了单列时速453公里、相对交会时速896公里的惊人纪录。这意味着当两列CR450擦肩而过时,它们之间的相对速度约为音速的 0.7倍,空气压力波冲击、气动噪声激增、车体结构承压等一系列极端工况同时叠加。邵军坦言,从CR400到CR450,时速从350公里跃升至400公里,这50公 里的突破进入了"速度无人区","每一公里的提升都带来了指数级的技术挑战。" CR450何以能跑得如此之快?其背后是设计理念的全面革新。铁科院机辆所空气动力学及振动噪声研究室研究员白夜向《环球时报》记者介绍,随着列车运 行速度提升,气动阻力在总运行阻力中的占比大幅增加,时速达到400公里时,占比已超过90%,成为影响能耗与效率的主导因素。为此,CR450团队进行 了系统性的减阻优化。 对于旅客而言,最直观的感受是"加速更快"。数据显示,CR450动车组从起步到提速至时速350公里,仅需4分40秒,而当前运营的时速350公里复兴号动车 组则需要6分20秒,提速周期缩短了100秒。"在长途旅行中,这种提速优势会更加明显,"邵军说,"CR450投入运营后,能够进一步拉近城市间的时空距 离。" 【环球时报报道 记者 李迅 ...
