摘要: 直升机旋翼动平衡试验台是一种主要的直升机旋翼测试设备之一,对试验台进行动力学分析和建模可以提高试验台的控制精度和试验的效果.在分析试验台结构和功能的基础上,简化了桨叶变距拉杆的载荷,通过对自动倾斜器的受力分析,得出了旋翼系统的动态模型.通过对液压系统和旋翼系统的联合仿真,分析了系统在旋翼姿态变化时的动态响应和交互耦合影响,初步了解了系统在各种不同负载特性下的响应,为试验台的姿态调节、激振的精度提高和进行理论研究提供基础,并为地面旋翼试验台系统的设计和控制提供依据.

Abstract: The helicopter rotor test-bed is one of the main equipments to test the helicopter rotors. The testing effect and control accuracy can be improved by making kinetics analysis and building the model of the helicopter rotor test-bed. The helicopter rotor test-bed structure and functions were introduced, and the pitch link loads was simplified. The dynamic model of the helicopter rotor test-bed was built by making the force analysis of the swash plate. According to the simulation of the hydraulic model and test-bed model, the dynamic response and interactive coupling influence were studied in the different gestures of the rotor system. The system responses were made in different load characteristics. The modeling and analysis of the test-bed can give a theoretical support on the control of rotor gesture and improvement of the excitation accuracy, and be helpful for the design of the test-bed and control system.
