The invention discloses a turboprop engine vibration measurement sensor calibrating and measuring device, comprising a standard vibration station, a standard vibration sensor and a vibration sensor to be calibrated arranged on the standard vibration station, a working environment simulation device arranged near the standard vibration station, a charge amplifier, and a signal analyzing instrument. The charge amplifier is used to convert a first sensitivity charge signal acquired by the standard vibration sensor in a regular testing environment into a first sensitivity voltage signal and to convert a second sensitivity charge signal acquired by the vibration sensor to be calibrated in the simulated onsite working environment of the turboprop engine into a second sensitivity voltage signal. The signal analyzing instrument is used to compare and analyze the first sensitivity voltage signal and the second sensitivity voltage signal, to measure out the sensitivity of the vibration sensor to be calibrated in the simulated onsite working environment of the turboprop engine. The turboprop engine vibration measurement sensor calibrating and measuring device makes the turboprop engine vibration testing more reliable.
Description
technical field [0001] The invention relates to the field of aviation vibration measurement and testing, in particular to a calibration and measurement device for a turboprop engine vibration sensor. Background technique [0002] During the test run of any type of aero-engine on the ground bench, vibration tests are required to monitor whether the vibration in its working state exceeds the limit value specified in the technical requirements, so as to prevent the hidden danger of vibration damage to the subsequent aircraft during flight, so as to improve the quality of pilots. job security. For a long time, with the continuous development of aviation manufacturing technology, the structure of aeroengines has become more and more complex, and the requirements for its vibration measurement accuracy have become more stringent. Therefore, vibration measurement calibration technology is particularly critical. [0003] attached figure 1 It is a calibration device of a vibration s...
