Abstract
To meet the high impact resistance requirements for the power systems of unmanned surface vehicles(USVs)and to address the limitations in nonlinear stiffness of limiters and in evaluation of time-domain impact response systems for floating rafts,an impact resistance evaluation study is carried out.The impact loads are defined in accordance with the relevant naval standards,a finite element model of the floating raft is developed using the time-domain simulation method,and a nonlinear stiffness modeling method for limiters is incorporated.The dynamic response is systematically analyzed under two conditions,with and without limiters,in terms of acceleration,displacement and stress.The results indicate that all performance indices satisfy the allowable impact resistance requirements.The limiters constraine the relative displacement of elastic components,and ensure the safety of shaft effectively.All associated parameter variations are within allowable limits.This study confirms the good impact resistance of the floating raft.The proposed nonlinear modeling and evaluation method enhances the engineering applicability of impact response predictions,and provides a simulation and evaluation framework for the impact-resistance design of similar power systems.关键词
