Abstract

This paper reports on measurement of landing force of a fruit fly (Drosophila melanogaster) using a MEMS force plate. By measuring the landing force of fruit flies, we found that the maximum force correlated with the landing velocity, which varied from several to 80 times larger than its weight. The experimental result suggested that there was the threshold value of the maximum landing force per weight for legs, which determined that a fruit fly lands with contacting with six legs or colliding bodily to the ground according to the landing velocity. The threshold value was thought to be the maximum force capacity of legs during landing motion.
果蝇腿在着陆时的最大受力能力
本文报道了用微机电系统测力板测量果蝇(Drosophila melanogaster)的着陆力。通过测量果蝇的着陆力,我们发现最大的着陆力与着陆速度相关,着陆速度比果蝇的体重大几倍到80倍。实验结果表明,果蝇的腿有一个单位重量最大落地力的阈值,根据落地速度决定果蝇是用六条腿接触落地还是身体撞击落地。阈值被认为是在着陆运动中腿部的最大力量承受能力。
