FIELD: engines and pumps.
SUBSTANCE: invention may be used to define calibration characteristics of linear accelerometers of ranges higher than 10g. Calibration centrifuge comprises rotary platform with units of tested accelerometers fixation. Units of fixation are located symmetrically at preset distance from axis of platform rotation and are arranged in the form of angles, which are fixed by means of stops in two positions with the possibility of turn by 180°. At that axis of turn is combined with line of location of accelerometer sensitive element mass center, and measuring axes of accelerometers coincide with platform radius. Unit of angles fixation to platform is helical pair, nut of which is fixed to platform.
EFFECT: increased accuracy and simplified design.
