Karakterisasi Windbelt Sebagai Generator Listrik

Nur Untoro


Abstract—Research has been conducted to study
belt as electrical generators. This research aims to study the
aspect ratio of the ribbon to the ribbon flutter, the influence of
stress to flutter frequency, the influence of wind speed to
induction voltage, the effect of wind speed on the amplit
wind speed relationship to flutter frequency, wind speed
relationship to the power of wind belt . The results show that the
higger aspect ratio required lower wind speed to flutter. Test
results wind belt frequency with a fixed force of 5.88 N and wi
speed 3m / s to 5.5 m / s indicates the value of fixed frequency (111 ± 0.2 ) Hz . This fact shows the standing wave by fluttering
ribbon following the Melde’s law. Amplitude ribbons flutter
initially increases with increasing wind speed, but eventuall
almost constant amplitude. This occurs because the elastic force
who against the aerodynamic force was proportional with
amplitude, so that the amplitude is fixed. Wind belt electric
voltage generated increases with increasing wind speed. Wind
belt electrical power is directly proportional to the wind speed.
