摘　　要：在已有的多刚体动力学模型的基础上,对钢索单元之间的球铰进行柔性化,建立了高架索刚柔混合体动力学模型;采用嵌入多体动力学仿真软件ADAMS对海上横向干货补给过程进行了仿真计算,并与高架索多刚体动力学模型的仿真结果进行了比较分析。结果表明:海上补给高架索刚柔混合体模型与现有的高架索动力学模型相比,在反映高架索的动力学特性方面更加趋于实际,可以直接应用在工程实践中。Based on the existing multi-rigid-body dyna-mics model,a rigid-flexible-body hybrid dynamic model of highline for replenishment at sea is proposed with consideration of flexibility of spherical hinge.By using ADAMS,a software for the multi-body dynamics simulation,and applying the new model,the process of dry cargo replenishment at sea is simulated and analyzed in comparison with the common multi-rigid-body dynamics model.The results indicate that the rigid-flexible-body hybrid dynamic model is more practical than the existing model of highline and can be directly used in the engineering practice.
