Aujourd’hui j’ai test\u00e9 le banc m\u00e9canique Doppler qui permet de d\u00e9terminer la vitesse d’un chariot.<\/p>\n

En PDF le tuto de branchement, de param\u00e9trages et d’interpr\u00e9tation des r\u00e9sultats.<\/p>\n

Et en vid\u00e9os les diff\u00e9rentes manipulations !<\/p>\n

Bon TP \u00e0 tous<\/p>\n

Par exemple, j’ai mesur\u00e9 \u0394t=0,148s donc \u0394f=1\/\u0394t=1\/0,148=6,76Hz donc v=c x \u0394f\/fe=340 x 6,76\/40 000=5,7cm\/s<\/p>\n

et pour une autre acquisition j’ai mesur\u00e9 \u0394t=0,06568s donc \u0394f=1\/\u0394t=1\/0,06568=15,22Hz donc v=c x \u0394f\/fe=340 x 15,22\/40 000=13cm\/s<\/p>\n","protected":false},"excerpt":{"rendered":"
