摘要:【中文】本发明涉及一种新超声速飞行器振动环境外推方法,属于环境计算技术领域。该方法包括以下步骤:选定一种与新超声速飞行器具有相似气动外形的相似飞行器;依次测量相似飞行器的离散化振动数据,并对每次测量的振动数据进行傅里叶变换后计算得到振动量级,同时计算每次测量对应的动压;通过对不同测量次数的所述振动量级与对应的动压进行线性拟合得到线性拟合曲线的系数,并通过设定的置信区间上限对所述线性拟合曲线的系数进行修正;根据所述线性拟合关系以及新超声速飞行器的动压得到新超声速飞行器的振动量级。本发明实施例解决了现有飞行器振动环境计算方法不适用于新超声速飞行器,导致新超声速飞行器难以确定振动环境的问题。 【EN】The invention relates to a novel supersonic aircraft vibration environment extrapolation method, and belongs to the technical field of environment calculation. The method comprises the following steps: selecting a similar aircraft with a similar aerodynamic shape with the new supersonic aircraft; measuring discretization vibration data of similar aircrafts in sequence, calculating vibration magnitude after Fourier transform is carried out on the vibration data measured each time, and meanwhile calculating dynamic pressure corresponding to each measurement; carrying out linear fitting on the vibration magnitude of different measurement times and the corresponding dynamic pressure to obtain a coefficient of a linear fitting curve, and correcting the coefficient of the linear fitting curve through a set confidence interval upper limit; and obtaining the vibration magnitude of the new supersonic aircraft according to the linear fitting relation and the dynamic pressure of the new supersonic aircraft. The method and the device solve the problem that the vibration environment of the new supersonic aircraft is difficult to determine due to the fact that the existing aircraft vibration environment calculation method is not suitable for the new supersonic aircraft.
