基于ADAMS的船用刚柔耦合起重臂在三级海况下运动分析

Motion analysis of marine rigid-flexible coupling crane boom in third-grade sea state based on ADAMS

为研究船用起重机刚柔耦合起重臂在三级海况时所吊重物的运动响应,首先应用STAR-CCM+软件对船舶的六自由度运动进行仿真,生成船舶和起重机基座在三级海况下的运动曲线;随后在ANSYS APDL模块中对起重臂进行与ADAMS对接的柔性化处理;将基座运动曲线、起重机模型和柔性起重臂导入到ADAMS中对工作状态(变幅和回转)的起重机进行运动学分析,得到重物在不同工作状态下的三个方向的位移曲线。研究结果为后续的其他材料起重臂运动的研究和船用刚柔耦合起重臂的减摇设计等提供参考。

In order to study the motion response of the cargo lifted by the rigid-flexible coupling boom of the marine crane in third-grade sea state,STAR-CCM+software was used to simulate the 6-DOF motion of the ship and generate the motion curves of the ship and the crane base in third-grade sea state.Then in ANSYS APDL module,flexible treatment of the boom is carried out to connect with ADAMS.The motion curve of the base,the crane model and the flexible boom were imported into ADAMS to carry out kinematic analysis of the crane in different working states(luffing and rotation),and the displacement curves of the cargo in three directions under different working states were obtained.The research results can provide reference for the motion study of booms of other materials and the roll reduction design of the marine rigid-flexible coupling crane boom.
