摘　　要：电磁轨道发射作为电磁发射技术的重要分支,具有发射速度高、射速可调节等显著优势,被誉为改变未来战争样式的颠覆性技术之一。目前,电磁轨道发射技术仍然面临射击精度低及装置寿命短等关键瓶颈问题,这些都与电磁轨道发射装置所涉及的复杂电、磁、热和力等多领域耦合发射动力学行为密切相关,然而国内外对极端冲击条件下电磁轨道发射装置的系统动力学分析尚缺少成熟理论方法和技术手段。针对上述情况,从动力学建模、性能预测、优化设计等方面综合阐述近期电磁轨道发射系统动力学理论与设计方法的国内外研究进展,总结相应的研究方向和需求。随着电磁轨道发射装置的工程化发展,电磁轨道发射系统的建模与仿真应考虑发射环境的全系统因素,建立电磁轨道发射装置和发射环境耦合的发射动力学性能快速预测和优化设计系统,详细阐明电磁轨道发射装置和发射环境多领域耦合振动机理等基础科学问题,为电磁轨道发射装置系统动力学的深入研究和相关装备研制提供支撑。As an important branch of electromagnetic launch technology,electromagnetic rail launch has significant advantages such as high launch speed and adjustable launch speed,and is regarded as one of the disruptive technologies that will change the style of future warfare.At present,electromagnetic rail launch technology still faces key bottlenecks such as low firing accuracy and short device life.These are closely related to the complex multi-domain coupled electrical,magnetic,thermal and force launch dynamics behavior involved in electromagnetic rail launcher.However,there is a lack of mature theoretical methods and technical tools for the analysis of system dynamics of electromagnetic rail launcher under extreme impact conditions at home and abroad.In response to the above situation,the corresponding research directions and needs comprehensive with recent domestic and international research progress in the dynamics theory and design methods of electromagnetic rail launcher from the aspects of dynamics modelling,performance prediction and optimization design was presented in this paper.With the engineering development of electromagnetic rail launcher,the dynamics modelling and simulation should consider the overall system factors of the launch environment,a rapid performance prediction and optimization design system for the launch dynamics of electromagnetic orbital launcher coupled with the launch environment should be developed,the basic scientific issues such as the vibration mechanism of electromagnetic orbital launcher coupled with the launch environment in multiple domains should be elucidated in details,and provides support for in-depth research on the dynamics and equipment development of electromagnetic rail launcher.
