Two-stage damping device for domestic strapdown inertial navigation type aviation gravimeter

The invention discloses a two-stage damping device for a domestic strapdown inertial navigation type aviation gravimeter. The two-stage damping device comprises a base, a first-stage damping material,a middle mass block, a second-stage damping material and a mounting base which are sequentially arranged from bottom to top, wherein the base is used for being mounted and fixed on an airplane, and the mounting base is used for mounting and fixing the aviation gravimeter; vibration of the airplane is transmitted from bottom to top through the base and is gradually reduced, and finally the vibration is transmitted to the aviation gravimeter through the mounting base. According to the two-stage damping device for the domestic strapdown inertial navigation type aviation gravimeter, on the one hand, specific vibration reduction damping, rigidity and specific parameters of the middle mass block are provided, and the actual application requirements of the domestic strapdown inertial navigationtype aviation gravimeter a
