摘　　要：升船机下闸首工作闸门作为升船机的重要组成部分,主要用于控制和调节升船机的水位以及保障通航船只的安全进出。采用CATIA软件建立升船机下闸首工作闸门的精确参数化三维模型,并利用Abaqus软件建立与实际情况相符的有限元模型。在常载工况下,设定适当载荷和边界条件,通过有限元分析校核闸门结构的安全性和可靠性。根据有限元计算结果进一步对闸门结构进行优化,以降低闸门质量为目标,采用参数化方法定义设计变量,包括板厚、主梁间距等。通过修改闸门参数,再次进行有限元分析,以验证优化后的闸门结构的安全性和可靠性。经过优化设计成功实现了闸门质量降低21.3%的优化效果。所采用的CATIA和Abaqus软件相结合的方法简便可靠,能够全面反映闸门结构的受力特性。通过有限元分析和优化设计,成功提高了升船机下闸首工作闸门的质量,进一步增强了其安全性和经济性。As an important part of the ship lift,the working gate of the ship lift is mainly used to control and adjust the water level of the ship lift and ensure the safe entry and exit of navigable vessels.The CATIA software is employed to establish an accurate and parameterized threedimensional model of the lower sluice gate,while the Abaqus software is utilized to develop a corresponding finite element model that accurately represents the real-world conditions.Under normal operational conditions,appropriate loads and boundary conditions are applied to conduct a comprehensive finite element analysis,aiming to verify the structural integrity and reliability of the sluice gate.According to the finite element calculation results,the gate structure is further optimized,with the goal of reducing the quality of the gate,and the parametric method is used to define the design variables,including plate thickness,main beam spacing and so on.The gate parameters are modified and are again analyzed to verify the safety and reliability of the optimized gate structure.After the optimization design,the optimization effect of the gate quality is successfully reduced by 21.3%.The combined method of CATIA and Abaqus software is simple and reliable,and can fully reflect the stress characteristics of the gate structure.Through finite element analysis and optimized design,the quality of the main working gate is successfully improved,and its safety and economy are further enhanced.
