Through vibration testing and simulation methods. The vibration characteristics of multi-layer airborne equipment integrated platform was analyzed. The experimental and simulation results indicate that the lower order modes of the platform are related to the stiffness of the shock absorber; In X-direction vibration, the first mode of the platform plays a major role; In the Y and Z direction vibration, the second and third order modes of the platform play a major role; The simulated RMS value of the equipment basically consistent with the experimental value, which can provide reference for subsequent virtual experimental models.
