The model structure determination of nonlinear aerody namics is an very important problem in parameter identification of flight vehicle. In this paper, firstly, the mathematical descriptions of nonlinear aerodynamic model are given, and then based on the longitudinal and lateral motion equations of missile, analysis shows that collinearity problem must be existed in the model structure determination of nonlinear aerodynamics. Frequency analysis clearly shows that, under the usually situation, m_z~α and m_z~(ω_z) cannot be identified separately, and this reveals the reason that has puzzled researchers for many years. Because of the effect of the multicollinearity, traditional MSD methods such as AIC criterion, stepwise regression etc., are not suited for the MSD of nonlinear aerodynamics for controlled flight vehicle. At the end of this paper, the effect of accuracy of measured data to parameter identifiability is discussed.

非线性气动模型结构确定是飞行器参数辨识中极其重要的问题。首先给出了非线性气动模型的数学描述,在此基础上,以导弹纵向及侧向运动方程为例,首次系统地分析了有控飞行器非线性气动模型结构确定中必然存在的共线性问题。频域分析过程清晰地表明在通常的试验情况下,m_z~α及m_z~(ω_z)是不可单独辨识的,从理论上解释了国内外一直不单独辨识它们的原因所在。指出原有的模型结构确定方法,如AIC准则,逐步回归等已不再适用于非线性气动模型结构的确定。同时对参数的可辨识性也作了一定的讨论。

Based on the small deflection theory, the lateral motion equation of a marine riser conveying flowing fluid subjected to environmental loads is developed by use of finite element method. Sampling analysis is made on 15 storms of Bohai Sea to obtain sequences of wave height and current velocity dominated by wave and current respectively. Then the optimal types of distribution and corresponding characteristic values are determined. Simulation of an important sampling method is made to get the wave height and current velocity whose joint probability is 0 01. For the marine riser hinged on fixed platforms in shallow sea, the maximum stress of riser is regarded as the control condition to determine the combined design criteria and comparison is made with other methods.
