摘　　要：针对现有的高架索多体动力学模型无法模拟高架索在外部扭矩作用下产生的弯曲和扭转变形的力学特性问题,在现有模型的基础上,利用浮动坐标系和平移模态矢量阵理论将绳索单元柔性化,建立了高架索多柔体动力学模型,并用该模型对海上航行横向干货补给装置中的高架索进行了模拟和仿真。仿真结果表明:高架索多柔体动力学模型可以模拟海上补给高架索的横向高频振荡、轴向动张力振动、弹性性能三大动力学特性。To solve the problem that the existing multi-body dynamics model of highline cable can not be used to simulate the mechanical characteristics of highline cable, such as bending and reversing de-formation under the action of external torque, a multi-flexible-body dynamics model of highline cable is established to make rope flexible based on the modal vector matrix and floating coordinate system. It has been used to simulate the highline cable of dry cargo replenishment at sea. The simulation re-sults show that multi- flexible-body dynamics model of highline cable can simulate the mechanical characteristics of highline cable, such as high frequency oscillation, axial dynamic tension and elastic vibration performance.
