| 摘 要： | 介绍了飞行载荷参数识别方法的基本原理。基于飞行载荷与飞行参数之间存在着相关性,通过专门的飞行试验实测载荷和参数,利用回归技术建立载荷与参数之间的经验关系,将飞行测量的参数转换成飞机结构部件上的载荷。还介绍了把该方法使用于Ｆ－７尾翼载荷和Ｆ－６操纵面铰链力矩导数的参数识别的研究实例,并对其进行了相应的评述。研究结果表明了这种方法的可行性、可靠性及实用价值。

| Abstract: | This report briefly presents the philosophy of the parametric identification method of flight load.Based on correlativity between the flight load and flight parameters,an empirical re- lationship between load and parameters,by means of special flight measurementhas been estab- lished by regression analysis.Flight measuring parametric data are converted into load on the structural components of aircraft with the relationship.The examples of adopting this method to identify the load on tail of F-7 and the derivatives of hinge moment of control surface of F-6 are presented,and some relevant evaluation to them is also given. The study results show the feasibility,reliability and its practical values. |
