高速磁浮交通已明确纳入国家战略规划。发展高速磁浮交通技术已成为落实交通强国发展战略和推动交通强国建设的重要抓手。科技部在2023年12月4日发布《对十四届全国人大一次会议第2199号建议的答复》，明确表示将依托“十四五”国家重点研发计划，继续支持高速磁浮交通系统工程化技术与运营系统集成技术攻关，最终形成时速600 km高速磁浮试验线方案和商业运营成套解决方案。高速磁浮交通技术将为轨道交通可持续发展提供强大动力。
习近平总书记多次强调，“关键核心技术是要不来、买不来、讨不来的”。高速磁浮交通技术已成为世界轨道交通技术的“制高点”、全球科技竞争的“战略高地”。随着高速磁浮交通技术研究进入无人区，需要高度重视并进一步加快布局相关基础理论与关键技术研究。
2023年9月14—15日，国家自然科学基金委员会工程与材料科学部、数学物理科学部和计划与政策局在上海联合主办了第346期双清论坛“高速磁浮交通前沿技术及关键基础科学问题”。国家自然科学基金委员会党组成员、副主任、中国科学院院士陆建华出席本次论坛，中国工程院院士卢春房、中国工程院院士田红旗、同济大学研究员林国斌共同担任论坛主席。论坛围绕“满足高精度和高稳定性要求的高速磁浮轨道关键问题”“高速磁浮交通平稳性与乘坐舒适性关键问题”“高速磁浮交通悬浮导向关键问题”“高速磁浮交通牵引供电与节能关键技术”“高速磁浮交通流固耦合特性及环境相容性”五大议题充分论证，迭代共识，凝练关键科学问题，探讨系统性解决方案和路径，为科学基金在高速磁浮交通技术领域的资助布局和管理创新积极建言献策，以推动600 km/h 速度级高速磁浮交通技术的高质量发展。与会专家一致认为，应及时布局多物理场动力作用机理、悬浮导向智能抗扰控制、高能效牵引供电系统配置与控制、大气及地基环境作用与影响等方向的基础理论与关键技术研究，加快中国高速磁浮交通技术的应用发展，巩固中国在轨道交通领域的世界领先优势。
基于此，国家自然科学基金委员会交通与运载工程学科协同来自同济大学、西南交通大学、中南大学、国防科技大学、中国科学院电工研究所、浙江大学及中车青岛四方机车车辆股份有限公司、德国蒂森克虏伯磁悬浮公司等磁浮交通行业顶尖高校、科研院所和企业的专家学者，面向600 km/h速度级常导高速磁浮交通产业化发展的重大战略需求，策划出版了《前瞻科技》2023年第4期高速磁浮交通专刊。本期专刊全面反映了第346期双清论坛的主要报告内容和论坛学术成果，从高速磁浮交通系统制式、磁浮车线匹配、悬浮导向控制技术、气动设计、牵引供电与控制技术等方面阐述国内外研究进展，分析高速磁浮交通的关键技术，提出未来发展方向建议。
本期专刊的出版，旨在围绕国家重大战略任务、科技前沿重要领域和关键核心技术，促进学术交流，推动科技进步，期望能为相关学者的研究和政府部门的科学决策提供重要参考，为国家重大战略的实施提供重要支撑。
