Description

The pedagogical bicycle VEL 200 is a pedagogical support designed to do the parallel between the perception of physical phenomenas and their scientific expression.

It allows to apprehend by measurement, physical quantities as varied as pedaling speed, wheel speed, transmission ratio, moment on crankset, moment on wheel, braking moment, moment of inertia, acceleration of the wheel, instantaneous power , work, kinetic energy ...

The pedagogical bicycle allows to play jointly on braking effects (application of static resistance moment) but also the dynamic effects associated with the inertia of the wheel.

The variable ratio transmission also allows to study the effects of the transmission ratio,  of the moments and speed ratios.

All data necessary for educational use are viewable via a provided soft developed in LabVIEW for PC ( USB connection)

This application allows:

• To configure the application data
• To visualize the measured physical quantities
• To conduct simultaneous graphics drawings on as many ways as desired
• To realize graphic screen shots for the drafting of the reports
• To export the data ( compatibility excel type)
