Full-similar simulation of wire rope winding vertical lifting ship lift's integrated physical model

升船机设计和建设中,整体物理模型试验是研究和解决升船机运行中水力学、机电、控制等诸多问题的有效手段。结合前人研究成果,分别对承船厢、平衡重系统、塔柱结构、机械同步系统等钢丝绳卷扬垂直提升式升船机核心部分在模型设计中需满足的相似准则进行了初步分析,指出其全相似模拟还需满足的理论条件和设计思路,并主要对机械同步系统提出了全相似模拟的方法。最后探讨了升船机整体物理模型全相似模拟的可行性和必要性。

In the design and construction of ship lifts, the integrated physical model test is an effective means to study and solve hydraulics, machinery, electric, control and many other issues during the operation of ship lifts. Combining the previous research results, this paper respectively conducts the preliminary analyses of the similarity criteria that the model design must meet of ship chamber, balance weight system, tower structure, mechanical synchronous system and other core parts of the wire rope winding vertical lifting ship lift, points out the theoretical conditions and design ideas needed in its full-similar simulation, and mainly puts forward a full-similar simulation method of mechanical synchronous system. Finally, this paper discusses the feasibility and necessity of the ship lift＇s full-similar simulation.
