摘要
本文采用奇异值分解技术处理载荷识别方程组系数矩阵的病态问题,并将这一技术应用于某机平尾的地面振动载荷识别,得到了令人满意的结果,为该机平尾的飞行载荷识别提供了有关技术和经验。
In this paper,using the singular value decomposition technique,the problem ofan ill-conditioned coefficient matrix in the equations for identifying vibrationloads is processed.The technique is applied to identifying the vibration loadsacted on the tailplane of an aircraft on the ground.Some satisfactory results areobtained which provide some techniques and experiences for the flight loadsidentification of the aircraft.
