Mechanical filtering method of high-range acceleration sensor

Abstract

The invention relates to a filtering technology of a high-range acceleration sensor, in particular to a mechanical filtering method of a high-range acceleration sensor, and solves problems that the filtering technology of a conventional high-range acceleration sensor cannot prevent high-frequency noises from damaging the high-range acceleration sensor, is complicated in manufacturing process and high in production cost, and cannot meet the miniaturization requirement of the high-range acceleration sensor. The mechanical filtering method of the high-range acceleration sensor is realized through the steps as follows: a buffering layer is selected and used as an inner filtering structure, and a sensitive structure of the high-range acceleration sensor is adhered to the bottom surface of an inner cavity of a pipe casing of the high-range acceleration sensor through the buffering layer; and a frustum structure is selected and used as an outer filtering structure, and the area of the upper bottom surface of the frustum structure is larger than that of the lower bottom surface of the pipe casing of the high-range acceleration sensor. The mechanical filtering method is suitable for filtering the high-range acceleration sensor.

technical field [0001] The invention relates to a filtering technology of a high-range acceleration sensor, in particular to a mechanical filtering method of a high-range acceleration sensor. Background technique [0002] As an inertial device, high-range acceleration sensors are widely used in vehicles, testing, aerospace and other fields. There is usually high-frequency noise in the test environment of the high-range acceleration sensor, and the high-frequency noise will seriously affect the correct reading of the overload acceleration value of the rigid body by the high-range acceleration sensor. Therefore, in order to ensure the normal operation of the high-range acceleration sensor, it is necessary to filter the high-range acceleration sensor. The existing high-range acceleration sensor filtering technology mainly includes algorithm filtering, circuit filtering and mechanical filtering. Among them, although algorithmic filtering and circuit filtering can realize the f...
