摘要
Abstract
Most existing studies on vehicles with water-exit ice-breaking capabilities primarily focus on vertical ice-breaking,lacking investigations into the influence of oblique angles on ice-breaking performance.Therefore,a numerical model for the oblique water-exit and ice-breaking process of a vehicle was built based on the arbitrary Lagrangian-Eulerian(ALE)fluid-solid coupling algorithm.The effects of the oblique angle,initial velocity,and ice thickness on the load and motion characteristics of the vehicle were systematically analyzed.The results indicate that during the initial ice-breaking stage,the impact of the vehicle's conical head induces intense local stress concentration in the ice.This leads to the early initiation of radial cracks at the top surface,followed by failure originating from the center.The center of the resultant force on the vehicle deviates from its axis,causing an exacerbated deflection along the initial oblique direction.Additionally,this trend becomes more pronounced as the initial velocity and ice thickness increase.During the subsequent ice-breaking process,in low velocity and thick ice conditions for the θ=10° case,the vehicle's attitude follows a"deflection-recovery"pattern.In high velocity and thin ice conditions,it transitions to a"deflection-steady flight"pattern.The research findings provide reference for the design and development of polar cross-media vehicles.关键词
