Abstract

The invention discloses a standard combined acceleration output device based on a swing arm centrifuge and an electromagnetic vibrating table, which is used for generating standard combined acceleration formed by combining linear stable acceleration and sinusoidal acceleration. The device comprises the swing arm centrifuge and the electromagnetic vibrating table arranged at the tail end of a swing arm of the swing arm centrifuge, wherein the linear stable acceleration is generated by the swing arm centrifuge; the sinusoidal acceleration is generated by the electromagnetic vibrating table. According to the device, the metering and testing requirements of an acceleration meter under the condition of combination of the stable acceleration and the sinusoidal acceleration are met; the vibrating table is independently arranged at the tail end of the swing arm of the centrifuge, and the problem of deviation of a movable ring of the electromagnetic vibrating table under a centrifugal force field is solved by a reverse electromagnetic coil additionally arranged in the vibrating table; the device is compact in structure; standard components are adopted, so that the device can be flexibly mounted and dismounted, and is convenient to debug and maintain.

Description

technical field [0001] A standard compound acceleration output device based on a swing arm centrifuge and an electromagnetic vibrating table disclosed by the present invention belongs to the technical field of inertial sensor measurement and testing, and specifically relates to a compound acceleration device composed of a standard steady-state acceleration and a sinusoidal acceleration. output device. Background technique [0002] At present, the continuous development of inertial technology puts forward higher requirements for inertial measurement testing technology. In the past, the metrological testing of inertial instruments under the condition of a single standard input acceleration cannot meet the traceability of the output of inertial instruments in complex application environments. Moreover, the characteristics of the accelerometer value are different under the single acceleration action and the compound acceleration action, that is, the accurate compound accelerati...
