Abstract/OtherAbstract:
|
The ergometer is mechanically braked by a band in series with a spring. Each end of the band passes over one of two spherical ball bearings, and is attached to the free end of a spring steel bar mounted on the same plate as the two ball bearings. By means of a spindle and cogwheel the plate can be tilted in such a way as to vary the tension in the braking band. The spring steel bar is furnished with four strain-gauges coupled as a Wheatstone's bridge. The system forms a differential force transducer measuring the differences in tension between the two ends of the band. A force is, therefore, only recorded if the flywheel is moving, because at rest forces influencing the bar from the band will be opposite and equal. The ergometer offers certain advantages over the conventional mechanically braked ergometers because it has an electronic read out, and it can be used in field studies. It is independent of the attitude in relation to the vertical, and can thus be used on tilting platforms or in weightless conditions. |
