摘　　要：为了对大型载人潜器下潜拉动缆绳瞬间引发的张力冲击过程进行研究,并分析相关因素的影响规律,采用集中质量法进行缆索系统建模仿真,得到缆绳张力和潜器速度变化过程。结果表明,潜器垂向附加质量、全排水量和缆绳弹性模量对缆绳冲击张力均具有影响,但前者影响微弱,后两者影响程度较强。这3个因素均不会显著改变潜器运动特性,潜器始终处于低速状态。减小缆绳弹性模量是降低冲击张力较为可行和有效的办法。In order to research on the cable tension shock process in the submersible dragging the cable to dive,and analyze the influence degree of relevant factors.The paper uses the lumped mass method to model and simulate the cable system,and obtains the change process of cable tension and submersible velocity.The results show that the submersible vertical added mass,whole array mass and the cable elastic modulus have influence on the cable tension,but the first factor has a weak influence,and the latter 2 later factors have a great influence.However,the 3 factors will not change the submersible’s motion characteristics,the submersible keeps low speed.Reducing the cable elastic modulus is a feasible and effective way to reduce the cable impact tension.
