| Abstract: | Guided missile body before launched is influenced by the vibration of aircraft, creating elastic vibration. The vibration can damage missile body and internal instrument. Finite element method is used to establish finite element model for missile body, deriving the natural frequency equation and forced vibration differential equation. The vibration response of missile body is calculated with the equation to determine a method and measure to reduce the vibration. |
