| Abstract: | A theoretical model for dynamic load identification is proposed with the help of motion differential equations of a multidegree - of - freedom system and geometry equation of a structure. It is then applied to identify a shooting load. The experimental analysis on a gun shield plate was also performed, and the measured and identified results agree well. Meanwhile, a new experiment method is given. |
