摘要：
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. © 2016, Editorial Department of Journal of HEU. All right reserved.
