Wherein, delta0The flexibility coefficient of the airport oil depot storage tank is shown, the reciprocal of the flexibility coefficient is the initial rigidity coefficient of the airport oil depot storage tank, and m is0The initial weight of the airport oil depot storage tank under the zero liquid level height when the monitoring system is initially set; in the actual measurement process, the liquid level height can be changed, so the actual measurement main frequency omega of the vibration of the airport oil depot storage tankaCan be represented by formula (2):
wherein Δ maFor the real-time weight and the initial weight m of the oil depot storage tank in the airport0A difference of (d); by combining formula (1) and formula (2), the calculation formula of the actually measured flexibility coefficient of the airport oil depot storage tank shown in formula (3) can be derived:
finally, actually measuring the vibration of the airport oil depot storage tank obtained in the step 3)Dominant frequency and theoretical dominant frequency omega of airport oil depot storage tank vibration obtained in the step0Calculating an actually measured flexibility coefficient of the airport oil depot storage tank by replacing the formula (3), finally obtaining an actually measured rigidity coefficient of the airport oil depot storage tank by taking the reciprocal of the actually measured flexibility coefficient, and then entering the S15 stage;
5) and S15 stage for judging whether the health condition of the storage tank of the airport oil depot is safe: in the stage, the airport oil depot storage tank structure health evaluation module (9) compares the measured rigidity coefficient of the airport oil depot storage tank with a theoretical rigidity coefficient obtained according to theoretical known quantity or empirical known quantity to judge the health condition of the airport oil depot storage tank structure, and if the measured rigidity coefficient is close to the theoretical rigidity coefficient, the health condition of the airport oil depot storage tank is judged to be safe, and the airport oil depot storage tank structure directly enters the stage S17; if the actually measured stiffness coefficient is smaller than the theoretical stiffness coefficient, judging that the health condition of the storage tank of the airport oil depot is dangerous, and entering an S16 stage;
6) stage S16 of safety early warning of airport oil depot storage tanks: in the stage, an airport oil depot storage tank structure health early warning module (8) sends out early warning information and stores an alarm log, and then the stage S17 is entered;
7) and (4) outputting an airport oil depot storage tank health condition analysis report in an S17 stage: in the stage, an airport oil depot storage tank structure health condition analysis report is generated by an airport oil depot storage tank structure health evaluation module (9) and stored in a background server (6), and the evaluation is finished.
