裕溪船闸三角闸门新型防撞结构体系研究

以裕溪一线船闸扩容改造工程中34 m口门三角闸门为研究对象,提出一种新型的三角闸门防撞结构体系,该结构由铝制蜂窝面板和刚性支撑杆件组成。对新型防撞结构体系进行有限元建模,并进行撞击模拟,同时将新型防撞结构体系与传统刚性防撞结构体系进行对比。结果表明:新型防撞结构体系在计算工况下工作状况良好,没有出现塑性;与传统刚性防撞结构相比,在消能、轻质和更换方面具有很好的优势。

Research on new anti-collision system for triangle gate of Yuxi ship lock

Taking the 34 m gate of the expansion and reconstruction project of Yuxi first ship lock as the research object,we propose a new type of anti-collision structure system of triangle gate,which is composed of aluminum honeycomb panel and rigid supporting bars. We establish the finite element model of the new anti-collision structure system,carry out the impact simulation,and compare the new anti-collision structure system with the traditional rigid anti-collision structure system. The results show that the new anti-collision structure system works well under the calculation condition,and there is no plasticity. Compared with the traditional rigid anti-collision structure,it has good advantages in energy dissipation,lightweight,and replacement.
