摘要
利用壳体、梁与块体单元建立某大型升船机有限元模型,运用通用有限元软件ADINA对该升船机结构进行动力特性分析。在模拟过程中,采用壳体-实体过渡单元来解决壳体与实体单元连接时自由度不同的问题。大型升船机塔柱结构模型的动力特性计算结果为大型升船机塔柱的动力分析提供了参考依据。
In order to study dynamic characteristics of the large ship-lift, the finite element model of tower structure of certain large ship- lift is established with software ADINA by shell, beam and solid elements. During the process of the simulation, shell-solid transition element is used to solve the different degree between the shell element and the solid element when they are connecting. The results of tower structure of the large ship-lift provide reference for seismic analysis of the large whole ship-lift.
