Analysis and Research on Structural Dynamics of Three-Axis Flight Simulator
This paper mainly aims at analyzing and researching on the dynamic characteristics of the three-axis flight simulator based on O-U-T type, by using multi-physical field analysis ALGOR. The paper gives out the low-order natural frequencies of three-axis simulator and its corresponding vibration modes under real load, and also presents the dynamic characteristics of harmonic response, transient response and response spectrum analysis under the influences of constraint and excitation. From the simulation results, found structure design and material property greatly affect on the dynamic performances of the simulator, confirmed the structure can meet its performance indicators and frequency response requirements. This is not only provide the evidence for structural optimization design and option evaluation of other similar simulation turntables, but also can be served as a useful reference for designing and debugging the control system of the simulators.
