Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to an integrated vibration reduction structure for a MEMS inertial instrument system. Background technique [0002] MEMS inertial instrument is a new type of inertial instrument manufactured on the basis of microelectronics and micromechanical technology. It mainly includes MEMS gyroscope and MEMS accelerometer. It has the advantages of small volume, weight, power consumption, high integration, resistance to harsh environments, and low cost. It is used in the fields of short-term autonomous navigation and attitude stability control. [0003] MEMS inertial instruments are generally composed of a meter head and a measurement and control circuit. A common form of meter head packaging is LCC ceramic shell packaging. In actual use, the ceramic shell is usually welded to the corresponding printed circuit board by surface-mounting. , and the printed circuit board and the housi...
