摘要
简述了一套测力系统的结构及其各部分组成。该装置设计以能提供恒定阻力为出发点,将不同系统进行有效组合,形成一个完整的能有效测量并能直接读取阻力值的阻力装置。该装置可方便快捷地设置阻力值大小,易于操作。
This device has been designed mainly for outputting constant mechanical resistance forces （F） for swimmer. As per the velocity （V） of swimmer, the mechanical power of each swimmer has been calculated through power formula P=F＊V. The resistance system includes brake disk, brake pads, ratchet wheel, mechanical spring equipment, indicator of mechanical force, support screw, and bolt, etc. The innovative characteristic of the device is that the resistance can be set validly and accurately. The ratchet wheel has been used to execute multiple tests repeatedly to swimmer after finish one-time setting the force, without rechecking resistance.
