摘　　要：目前,皮艇项目的实船动力学测试手段和装备十分匮乏,其瓶颈在于对桨力的测量.针对这一现状,通过分析皮艇运动过程中杆的受力及其应变状态,根据项目的特点,设计了一种偏置型皮艇桨力传感器.这种传感器不破坏桨体结构,可快速安装和拆卸,实现了一个传感器在多个桨杆之间轮换使用.目前,中国国家皮艇队的实船动力学测试系统均配备这种结构的桨力传感器,经过多次批量测试,测力方法的正确性和可靠性得到了充分验证.There is a grave shortage of test methods and equipments for real-boat kayak dynamic parameter evaluation. The key difficulty is a simple and rapid measurement of oar force. A novel oar force sensor was developed to solve this problem. The new sensor can be fixed on a paddle and disassembled easily and can be reused between multiple paddles. Now, the measurement systems used by the Natronal Kayak Team of China are all equipped with the new sensor. Experiment results demonstrate the validity and reliability of the oar force sensor. The mechanical structure, force-measuring principle and calibration methods are discussed in detail.
