摘要
跨介质航行器高速入水过程涉及多相流场与物体间复杂的流固耦合作用,航行器面临瞬态冲击载荷极易发生结构损坏。文中综述了目前国内外跨介质航行器高速入水载荷特性和降载方法的研究进展,总结了常见降载方法并分析其优劣,提出了未来跨介质航行器高速入水降载研究的重点发展方向。
The water entry process of high-speed vehicles involves complex fluid-structure interaction between multiple phase flows and vehicles,which can result in transient impact loads and potential structural damage.In this paper,a brief description of the high-speed water entry impact problem for vehicles is provided,with a focus on the current development of active and passive load reduction methods for vehicles.Additionally,the paper provides a summary of the advantages and disadvantages of common methods for reducing water entry loads,and elucidates the key research directions for reducing water entry loads of vehicles,aiming to provide a reference for further study on the characteristics of water entry loads and the load reduction methods of vehicles at high speeds.
