| Abstract: | The displacement of the solid rocket is obtained by the integration of the low-frequency vibration during free flight state. Then by the modal superimposition method,a method for identifying the transverse load of solid rocket is introduced. Based on an example of solid rocket remoting data,the results of transverse bending moments are given. Identified result and measured cross section bending moment are approximate,proving that such a method is practical in load identification for similar problems and muc... |
