摘要
针对现有防撞拦阻系统与船舶大型化发展不相适应的问题,进行主动式安全拦阻方案的相关研究。通过机械臂自主套缆,阻拦索上的拉力通过刹车带、导带轮传递至摩擦吸能单元,由摩擦吸能单元上的摩擦制动器在制动距离内逐渐吸收船队的动能等系列方法,保障船队过闸期间安全停靠,消除船舶失速、超速撞击船闸人字门的安全风险。同时通过数值模拟仿真验证拦阻方案的可行性和有效性。结果表明:该方案可满足8 750 t(空载)~3万t(满载)载质量排水量范围的成组过闸船队,0.5 m/s进闸航行速度,在20 m制动距离内减速制动,安全停船,有效保证船闸人字门和成组过闸船队安全。
Regarding the problem that the existing anti-collision arresting system does not adapt to the new situation of large ships and formation of new ships,an active safety arresting scheme of large ship locks is proposed.By using a robotic arm to autonomously lay cables,the tension on the blocking cable is transferred to the friction energy absorption unit through the brake belt and guide pulley.The friction brake on the friction energy absorption unit gradually absorbs the kinetic energy of the fleet within the braking distance,and a series of methods are used to ensure the safe parking of the fleet during the lock period,eliminating the safety risks of ship stalling,speeding and hitting the ship s gate.At the same time,The feasibility and effectiveness of the arresting scheme are verified by numerical simulation.The results show that the scheme can satisfy a group of lock passing fleets with a displacement range of 8,750 t(no load)~30,000 t(full load),the entering speed of 0.5 m s,the braking speed of 20 m braking distance,and the safe stopping of the ship.The safety of the miter gate of the ship lock and passing fleet are effectively ensured.
