The invention discloses a calibration and measurement device and method for a vibration sensor at a turboprop engine fuel adjustment place. Calibration and measurement device for the vibration sensor of the turboprop engine fuel adjustment department, including the vibration table for simulating the vertical vibration frequency of the turboprop engine, the standard vibration sensor and the vibration sensor to be calibrated on the vibration table, and the power amplifier for signal amplification , a signal analyzer for collecting and generating signals, a controller for comprehensive control, and a power supply; the input terminals of the signal analyzer are respectively connected to the standard vibration sensor and the vibration sensor to be calibrated, and the output terminal of the signal analyzer passes through the power amplifier Connect to the vibration table; the controller is connected to and controls the signal analyzer; the upper end of the vibration sensor to be calibrated is provided for assisting in calibrating the vibration sensor to be calibrated and after disassembly, the vibration sensor to be calibrated is directly connected to the fuel regulator of the turboprop engine to measure the fuel consumption of the turboprop engine. Auxiliary calibration device for adjusting vertical vibration value.
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 ...
