船用起重机伸缩套管减摇装置原理和实验

针对船用起重机在海上作业过程中，由于悬挂重物的钢丝绳属于柔性件，加上风、浪等海洋环境载荷的影响，使得负载产生摆动。基于起重机海上作业时吊物的摇摆,设计开发了一种新型船用起重机伸缩套管减摇装置，利用套管的刚性约束来减小吊索的摇摆幅度，利用万向力矩结构减轻套管的受力，套管通过万向力矩运动时，依靠弹簧阻尼来存储释放能量，减少吊重的摆幅。介绍了伸缩套管装置的结构和原理，建立船、起重机、伸缩套管的数学模型，并利用Adams建立仿真模型进行运动学分析，得出伸缩套管装置具有明显的减摇效果，同时通过搭建实验平台进行实际实验，验证了伸缩套管装置在实际应用中的也具有显著的减摇效果。

Principle and Experiment simulation of the telescopic casing anti swing device of offshore crane

For offshore crane in the operation process at sea, due to the suspension of lifting wire rope belongs to the flexible parts ,also wind, wave and ocean environment to inflect the load. These cause the load swing .A new type of offshore crane telescopic sleeve stabilizer was proposed based on the work condition of crane at sea .It uses the casing of the rigid constraints to reduce the swing range of the load, and using the universal torque structure to reduce the stress of the casing . When the casing is moving through the universal torque structure . Rely on the spring dampers to store and release energy. By these methods to reduce the swing of load . The telescopic sleeve device was introduced. A mathematical model of the ship, crane and telescopic sleeve is established. The kinematics analysis of the simulation model is carried out by using Adams. Verify the obvious damping effects of the telescopic sleeve device . At the same time, through constructing the experimental platform for actual experiments,Verifying the telescopic sleeve device in the practical application of also has significant effect of damping.
