摘要
针对直升机绞车收放时缆位保持问题,建立了负载出水回收进舱阶段缆位的动力学模型。由于浮力与洋流作用突然消失,负载出水后发生摆动,将负载的摆动作为带有理想约束的质点系动力学系统,采用拉格朗日方程建立动力学模型。考虑直升机悬停提升的情况进行仿真,仿真结果表明建立的数学模型能够较好的模拟负载摆动时的缆位变化。
The dynamic model of cable orientation during recycling using winch above the sea is established to solve the problem of keeping the cable orientation in helicopter. Due to the sudden disappearance of ocean current and buoyancy, the load begins to swing. The sway of the load can be considered as dynamic of particle system with ideal constraint condition. The dynamical model of cable can be established through Lagrange equation. In consideration of the recycling during helicopter hovering, simulation results show that the cable model is feasible which simulate curves of the cable during the sway of the load.
