摘要
为深入研究深海绞车系统在地质取样、海底生物拖网取样和吊放仪器等作业中的应力状态变化规律,保证其安全性,根据不同转速下深海绞车开展海底取样作业时的工作状态,建立储缆绞车和牵引绞车的物理模型和数值仿真模型,进行刚柔耦合动力学分析。对储缆绞车和牵引绞车的Mises等效应力随转速和时间的变化规律进行系统分析,并验证所设计模型的正确性,为深海绞车系统的机械设计和优化提供参考。
In order to deeply study the stress state change law of the deep-sea winch system in geological sampling,seabed biological trawl sampling and lifting instruments,and ensure its safety,according to the working state of the deep-sea winch when carrying out seabed sampling operation at different speeds,the physical model and numerical simulation model of the cable storage winch and the traction winch are established,and the rigid-flexible coupling dynamics analysis is carried out.The variation law of Mises equivalent stress of cable storage winch and traction winch with speed and time is systematically analyzed,and the correctness of the designed model is verified,which provides a reference for the mechanical design and optimization of deep-sea winch system.
