【摘要】 目的研制赛艇划桨力的实船测试装置。方法设计了一种马蹄形测力传感器,可安装于桨栓,不妨碍运动员正常划船,也又不改变船体原有结构。结果实验条件下具有良好的线性力-应变关系,可以保证实际应用时传感器的电输出与划桨力成正比。结论提出了可应用于实船实时测试水上运动员划桨力的一种测力传感器。试验结果表明,这种测力传感器可以有效监测划桨板的受力状况。更多还原

【Abstract】 Objective To develop a sensor for measuring oar force in rowing real time. Methods A horseshoe sensor was developed to be easy to fix to the thole of gig. The mount of sensor does not change any structure of the gig. The rowing of athletes will not be obstructed by force measurement. Results The linear load-strain relation was measured in the laboratory experiment. Such linear relationship ensures that the electrical output of the sensor is proportion to the oar force exerted by athletes.更多还原
