Research on Combined Vibration Test Method for the Launcher Equipment of Airborne Missile

Objective To study the vibration test method for the launcher equipment of airborne missile. Methods Based on the vibration environment test, the dynamical responses characteristics of structures on the launch equipment and the dummy missile were gained. Through comparing the characteristics with the flight data, a simulation principle of flight loading was developed. A new combined vibration test method was proposed according to the vibration characteristics and flight loading. Results The vibration environment test of the launcher under the combined effects of mechanical condition and vibration was realized. Conclusion In the paper, the vibration test technology using the superposition of static loads for launcher was discussed, which was closer to the air working condition of the launcher
