摘要
基于对共轴双旋翼桨叶的动力学和空气动力学分析,建立了共轴双旋翼试验台液压操纵系统模型,并通过simulink仿真分析了系统在俯仰操纵和高频激振时系统的动态响应和交互耦合影响,为地面旋翼试验台系统的设计和控制提供依据。
A model of the hydraulic servo control system of coaxial twin rotor experimental bench was founded based on flight dynamics and rotor aerodynamics.The dynamic characteristics and the interactive coupling of the system when the input signal is forward flight and high frequency excitation was posted by the simulation which based on the mathematical model and the use of Simulink.The conclusion of the simulation can be a guidance when designing the structure and the control system of the rotor experimental bench.
