DEVICE FOR CONTROLLING ADDITIONAL NON-LINEARITY OF MICRO-ELECTROMECHANICAL CONVERTERS OF LINEAR ACCELERATION DURING VIBRATION RESISTANCE TESTING

摘要

FIELD: measuring equipment.;SUBSTANCE: invention relates to metrology and is intended to control additional non-linearity of micro-electromechanical converters of linear acceleration (MCLA) during testing of vibration resistance. Device for control of additional non-linearity of converters of linear acceleration during testing of vibration resistance comprises a vibrator, rigidly fixed on the device, which is rigidly fixed on the shaft of the goniometric device. On the vibrator table there are fixed a vibration sensor and a tested micro-electromechanical converter of linear accelerations, the output of which is connected to the input of the converter, the output of which is connected to the input of the computer, while the output of the vibration sensor is connected to the input of an oscillograph and to the input of a vibration meter. Output of the shock table generator is connected to the input of the shake table amplifier, the output of which is connected to the input of the shock table. At that, the device includes a level, adjustment screws with the help of which the shock table is put into a horizontal position controlled by the level; the device includes a vibration-absorbing gasket made with a possibility to reduce vibration.;EFFECT: increase in accuracy.;1 cl, 1 dwg
