| 目的 提出一种用于实船测量的风帆推力测量方法。方法 针对VLCC风帆推力实船测量的需求，首先对风帆推力计算公式和风帆桅杆推力状态进行分析，进一步根据梁结构应变测试方法提出基于应变监测的风帆推力测量方法和传感测点布置方案。通过陆基模拟试验对风帆推力测量方法进行试验验证。结果 传感测点间结构应变差值随风帆推力增加而增大，具有显著线性关系，线性相关系数为0.9965，测试风帆推力与实际推力之间的平均误差为5%。结论 提出的风帆推力测量方法用于实船测量是切实可行的。 |

| 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. |
