桥墩主动防船撞系统的研究

Study on Pier Initiative Collision Avoidance System

为确保桥梁水域桥墩安全与船舶通航安全,通过对长江水域船舶通航环境与水域安全现状以及船撞桥事故统计分析,提出开展桥墩主动防船撞系统研究的必要性。利用船舶操纵理论与船间水动力干扰相关理论,建立了船间临界失控水动力干扰模型,并据此建立了桥墩主动防船撞系统,将桥墩由被动结构防船撞转变为非结构主动防船撞,并在此基础上开发出了桥墩主动防船撞系统原型。创新之处在于,首次利用船舶操纵理论与船间水动力干扰相关理论,建立了船间临界失控水动力干扰模型,首次将桥墩的被动防撞转变为桥墩主动防撞,并开发出桥墩主动防船撞系统原型。

To ensure pier safety and ship navigation safety in pier waters, through analysis of ship navigation environment in Yangtze River and statistics of collisions between ship and pier, necessity of exploitation of pier initiative collision avoidance system was demonstrated. With theories of ship maneuverability and ship hydrodynamic interaction, model of ship critical uncontrollable hydrodynamic interaction was put forward. System prototype of pier initiative collision avoidance system was studied with the new system prototype.
