【摘要】：軟管-錐套隨加油機(jī)在空中飛行時產(chǎn)生的飄擺運動增加了受油機(jī)安全準(zhǔn)確地對接加油錐套的難度,采用多剛體動力學(xué)建立空中加油軟管-錐套在尾渦流場及大氣紊流下的空中飄擺運動的數(shù)學(xué)模型,分析了加油機(jī)在不同飛行條件下軟管-錐套的平衡拖拽尾跡以及氣流對軟管-錐套的影響。為了減小軟管-錐套空中飄擺運動的幅度,對軟管-錐套運動設(shè)計了控制器。在對非線性模型線性化及降階處理的基礎(chǔ)上,設(shè)計了PID(proportion-integration-differentiation)控制器。仿真表明所設(shè)計的控制器能有效減小軟管-錐套的運動幅度,從而能夠降低空中加油對接的難度,提高空中加油的安全性。
[Abstract]:The fluttering motion of the hose cone sleeve with the tanker flying in the air increases the difficulty for the receiving unit to docking the refueling cone sleeve safely and accurately. The mathematical model of floating pendulum motion of air refueling hose and cone sleeve in the wake of eddy current field and atmospheric turbulence was established by using multi-rigid body dynamics. In this paper, the equilibrium towing wake of the hose-cone sleeve and the effect of air flow on the hose-cone sleeve are analyzed under different flight conditions. In order to reduce the range of floating pendulum motion in the air, a controller is designed for the motion of hose-cone sleeve. On the basis of linearization and order reduction of nonlinear model, a PID-proportion-integration-differentiation controller is designed. Simulation results show that the designed controller can effectively reduce the motion amplitude of the tube-cone sleeve, thus reducing the difficulty of aerial refueling and docking, and improving the safety of aerial refueling.
