摘要
Abstract
Motion system is one of the main subsystems of the virtual environment of flight simulators. Buffet simulation is an important content for the motion system to improve the fidelity. In this paper, a buffet model is established by using the basic model of sinusoidal and random hybrid vibration, combined with the acceleration power spectrum density (APSD) of the aircraft flight test vibration data. Based on the APSD, an estimate method of buffet parameters is studied to calculate the parameters of the sinusoidal and random components. The vibration characteristics of typical flight conditions are analyzed, and an extraction method of influence parameters is studied to achieve the buffet model under full flight condition. Driven by the buffet parameters and the influence parameters, a modeling method for the buffet analysis is proposed. The results show that this method can effectively simulate the buffet in flight simulator systems. Moreover, this study provides a reference for the construction of vibration environment in virtual reality technology.关键词
