移动载荷激发冰层水弹性波的研究进展
Research progress on hydroelastic waves excited by moving loads on an ice sheet
摘要
Abstract
In polar ice-covered regions,wave motion at the ice-water interface is governed by a restoring force comprising both gravity and the elastic force of the ice layer.Such waves are known as hydroelastic waves(or flexural-gravity waves).Unlike ocean surface waves,the propagation characteristics of hydroelastic waves are governed not only by hydrodynamics but also significantly depend on the elastic properties of the ice layer.Its critical resonance regime differs entirely from pure gravity waves,exhibiting unique nonlinear wave phenomena near the critical velocity.This paper systematically reviews research progress on hydroelastic waves excited by moving loads,covering theoretical studies,numerical simulations,and experimental observations.Key aspects include potential flow models,viscoelastic effects,nonlinear dynamics,and ice sheet dynamic characteristics under complex motion scenarios(such as accelerated motion,3D effects,channel boundaries,and submerged loads).The study reveals that viscoelastic and nonlinear effects are key mechanisms explaining the finite-amplitude response at critical velocities,while the propagation characteristics of hydroelastic waves in complex motion scenarios further demonstrate the diversity of ice-water coupling interactions.This paper provides critical theoretical and technical insights for polar resource exploitation,ship navigation safety,and the design of large-scale floating marine structures.关键词
