Study on the Method of Making Free Flight Vibration Profile for Air-to-air Missile Based on Measured Data

Objective To analyze and study the free flight vibration environment of air-to-air missile based on the measured data, and to discuss and recommend the formulation method of free flight vibration test condition for air-to-air missile. Methods The data was processed and analyzed considering the particularity of vibration data of air-to-air missile. Results The spectra of vibration response of air-to-air missile in each area were obtained after processing of the measured data, and the ground test profile was obtained through the ground test and dynamic simulation analysis and revision. Conclusion To formulate a reasonable free flight vibration test condition for air-to-air missile, the analysis should be based on the measured data, under the condition of appropriate vibration implementation.
