固体火箭横向响应载荷识别方法

利用小波分析在时频两域都具有表征信号局部特征的特点，对固体火 箭飞行遥测过载数据进行了小波分解，然后从结构动力学理论出发提出了一种识别固体火箭 截面剪力和弯矩的方法。结合某型固体火箭的遥测参数对火箭主要截面弯矩和剪力进行了 识别，给出了识别结果。该方法对自由-自由飞行的固体火箭截面横向载荷的评估及设计 具有重要的参考意义。

The Identification Method of Transverse Responding Load for Solid Rocket

Using the capability of wavelet analysis to characterize the signal's local property both in frequency and time doma-in, the wavelet decomposition of flight remoting overload data was performed. Then through the structural dynamic theory, a meth-od for identificating the transverse load of solid rocket was introduced. Based on an example of solid rocket remoting data, the re-suhs of transverse shear force and bending moment were given. Such a method is practical in load identification for similar prob-lems and much useful in engineering.
