摘　　要：空中加油对接过程中,对软管-锥套的动力学行为的研究是空中加油过程建模的关键之一。为研究软管弯矩对软管-锥套系统动力学建模的影响,基于多刚体动力学,在质量-弹簧阻尼模型的基础上,建立了一种包含软管的弯曲和线弹性特性的动力学模型,分析了弯矩对软管影响的机理以及不同情况下弯矩对锥套扰动的影响。数值仿真结果验证了弯矩因素对软管-锥套系统动力学建模的必要性。The study of the hose-drogue system ＇s dynamical action is one of the keys in the docking process of aerial refueling modeling.In order to examine the effects of bending moment of the hose in dynamic modeling of aerial refueling hose-drogue system,this paper integrated the hose restoring force into mass-spring-damp model.Based on the multi-body dynamics,a dynamics model including bending and elastic characteristics is built.Numerical simulations for different flight conditions are carried out and the effects which the hose restoring force put on the deviation of drogue are analyzed.Finally,the simulation results show the necessity of the bending moment for dynamic modeling of aerial refueling hose-drogue system.
