基于MSC.ADAMS的起重船吊物系统动力响应仿真分析

摘要

Wave load can cause the floating crane lifting load to swing sharply, so that the offshore operation is forced to shut down. This paper establishes the swing 3D nonlinear dynamic differential equation according to Lagrangian equations. By virtual prototype technology, multi-cylinder system dynamic numerical simulation is analyzed and researched, and some parameters in the system is discussed including the sling length, the hoisting speed, etc. The results provide some valuable references for offshore construction.%波浪载荷作用会引起起重船吊重的大幅摆动,从而导致海上作业被迫停工.文中根据拉格朗日方程建立了吊物系统摆振三维非线性动力学微分方程.采用虚拟样机技术进行了多缸体系统动力学数值仿真分析研究,并对系统一些参数进行了讨论分析,包括吊索长度、起吊速度等,所得结论可为海上施工提供有益参考.
