| Abstract: | By means of the experimenfal frequencies and modes of a tactical missile,the paper has applied the method of redesigning structural vibration modes by inverse perturbation to change the solution of the airframe joints'c.ompHances of a tactical missile into the simple form of linear equations.The example indicates that the method in a better one to obtain the compliances of air-frame joints. |
