| The work aims to develop strain sensors suitable for safety monitoring of ships and marine engineering structures and propose calibration methods. In view of the characteristics of the marine environment, considering the sensor packaging technology, a strain sensor with elastomer and resistance strain gauges as the main components was developed through structural design and finite element simulation calculation. A special calibration beam for sensor was designed and the calibration process and data processing method research were completed. The calibration experiment was carried out to obtain the calibration data of the sensor as well as the conversion coefficient and nonlinear error of the sensor. Environmental and reliability test verification of sensors were carried out. The conversion coefficient of the sensor had a high consistency. The maximum value of the coefficient was 0.342. The minimum was 0.335. The deviation was 2.05%. The maximum nonlinear error of the test sensor was 1.3%. It has passed 9 environmental tests and 2.56 cycles of reliability assessment with a total of 1 980 hours. The calibration method presented is applicable. The sensor can withstand the long-term effects of temperature, humidity and salinity in marine environmental conditions and meet the monitoring needs of real ships. |
