摘　　要：为直接获得准确的风翼助航船舶风翼受力大小与方向,对于采用圆柱形桅杆的风翼系统,提出了通过采用测量桅杆弯曲应变间接获得风翼受力的测量方法。首先给出了采用电阻应变片组成的半桥差动电路设计的测量装置结构。然后在弯曲应变测量技术基础上,通过理论分析研究获得风翼受力大小与方向的测量方法。最后,通过大量的实验测量数据,验证了该测量方法的有效性与可行性。研究结果表明,该测量方法具有系统测量装置结构简单、安装与操作方便,测量范围大、稳定性与线性度好等特点,从而解决了一类风翼助航船舶推进控制系统的风翼受力测量问题。To obtain the accurate wing thrust and the direction of the thrust for wing-assisted ships with respect to the cylindrical wing-mast system,we propose a measurement method for obtaining wing thrust by measuring the bending strain of the mast. First,we discuss the structural design of the measurement device with a resistance strain gauge based on the half-bridge differential circuit. Based on the bending-strain measurement technology,we use theoretical analysis to obtain the wing thrust and direction. Finally,we carry out numerous experiments and analyze the measurement data to verify the effectiveness and feasibility of this method. The research results show that the measurement system device has the advantages of a simple structure,convenient installation and operation,wide measurement range,and good stability and linearity. As such,we validate the proposed wing-thrust measurement method for wing-assisted-ship propulsion control systems.
