| Abstract: |
| This paper aims to propose a measurement method of sail thrust for real ship measurement. According to the requirement for thrust measurement of VLCC sail booster, the calculation formula of sail thrust and the mechanical state of the sail mast are analyzed, and then according to the strain measurement method of beam structure, the sail thrust measurement method and layout scheme of the measurement sensors based on the structural strain monitoring technology are proposed. The measurement method for sail thrust is verified by land-based load test. The results show that the structural strain difference of the measuring sensors increases with the sail thrust increasing, showing a significant linear relationship, and the linear correlation coefficient is 0.9965. The average error between the tested sail thrust and the actual trust is 5%. The proposed measurement method is feasible for real ship measurement. |
