Abstract. In order to know well the vibration law on influence of ground vibration on instrument support in gun firing process, a measuring method for the vibration response of the instrument support based on the principle of acceleration measurement is presented. The instrument support is arranged on the ground. When the gun fires, the acceleration response of the instrument support is measured. The vibration velocity and vibration displacement responses of the support can be obtained by the integral operation of the acceleration. The results show that when the gun fires with single shot and the period of the projectile in-bore motion, the vibration response of the instrument support caused by ground vibration is very small, and it can be ignored. When the projectile moves outside the bore, the ground vibration has a significant influence on the vibration of the instrument support. The vibration response of the instrument support in the range of muzzle shock wave is mainly caused by the muzzle shock wave.
