The invention discloses an apparatus and method for calibration and measurement of a vibration test sensor at a fuel regulator for a turboprop engine. The apparatus for calibration and measurement of a vibration test sensor at a fuel regulator for a turboprop engine comprises a vibration table which is used for simulating vertical vibration frequency of a turboprop engine, a standard vibration sensor and a calibrated vibration sensor, a power amplifier which is used for signal amplification, a signal analyzer which is used for signal acquisition and signal generation, a controller for integrated control and a power supply, wherein the standard vibration sensor and the calibrated vibration sensor are arranged on the vibration table; an input end of the signal analyzer is connected with the standard vibration sensor and the calibrated vibration sensor; an output end of the signal analyzer is connected with the vibration table through the power amplifier; the controller is connected with the signal analyzer and controls the signal analyzer; and the upper end of the calibrated vibration sensor is provided with an auxiliary calibrating device which can assist in calibrating the calibrated vibration sensor and can directly connect the calibrated vibration sensor with a fuel regulator for the turboprop engine after detachment of the auxiliary calibrating device so that the vertical vibration value of the fuel regulator for the turboprop engine can be measured.
Description
technical field [0001] The invention relates to the technical field of aviation measurement and testing, in particular to a calibration and measurement device for a vibration sensor at a turboprop engine fuel adjustment station. In addition, the present invention also relates to a method for calibrating and measuring the vibration measuring sensor at the fuel regulating station of the turboprop engine comprising the above-mentioned device for calibrating and measuring the vibration measuring sensor at the fuel regulating station of the turboprop engine. Background technique [0002] During the bench test run of a certain type of turboprop engine, the vertical vibration value of the fuel adjustment part of the aircraft needs to be measured according to the test process regulations, and it is used as one of the basis for product acceptance. During the test run, sometimes the vibration of this part is out of tolerance. In order to ensure that the vibration of the aircraft body ...
