深海勘探吊放绞车试验台设计与强度分析

Design and Strength Analysis of Test-bed for Deep-sea Exploration Dipping Winch

为了实现深海勘探用吊放绞车承载能力、主动升沉补偿能力、制动能力以及关键部件滑轮和缆索的承载能力测试,设计了一种基于塔式配重和液压驱动的组合型绞车试验台。针对试验台塔架的几何结构,分析了其在试验过程中绞车突然制动所承受的冲击载荷,以及塔架的约束情况。基于ANSYS有限元软件,利用梁、壳单元建立塔架有限元模型,对该塔架进行了静态分析,得到了各关键部位的应力、应变分布规律,提出了主要结构设计改进方案。建立的塔架有限元模型以及计算结果能为同类塔架的设计和优化提供理论依据。

In order to realize carrying capacity, active heaving and sinking compensation and stopping power of the dipping winch for deep-sea exploration and bearing capacity test of the key parts of the pulley and the cable, a combined winch test-bed based on the counterweight tower and hydraulically driven is designed. Aiming at the geometric structure of test-bed tower, the tower subjected to impact load by winch brake and its constraint condition during the test process are analyzed. Based on ANSYS finite element software, the finite element model of the tower is established. The static analysis of the tower is carried out. The stress and strain distribution of the key parts is gotten. Main structural design improvement project is proposed. The finite element model of the tower and calculation results can provide a theoretical basis for the design and optimization of the same tower.
