To measure the flight force, we design a two-axis force sensor that can measure the upward and forward forces while the dragonfly is flapping its wings.

The wing’s dynamical characteristics are measured using the base excitation method in conjunction with two laser displacement sensors. The laser displacement sensor can measure the motion of transparent targets. In this way, we can study the effects of reflective dots put on the dragonfly’s wings by other researchers. After collecting large experimental data, we compare the wing’s dynamical characteristics of dragonflies, of the same kind and different kinds. We also study the correlation between the flight force and the geometrical dimensions and dynamical characteristics of the wings. 盧中仁 2012 學位論文 ; thesis 119 zh-TW |
