屈曲運動生物を模倣した水中推進機構のシミュレーション : べん毛運動の場合

抄録

Organism are quite functional and the application of dynamics in organisms to the field of engineering is very instructive. To make an artificial propulsion mechanism by bending waves, a simulation study of a propulsion mechanism which imitated the bending motion of organisms in water was carried out. As the bending wave motion, flagellar motion, which depends on Stoke's law, was employed. In the simulation, the bending wave of the organism was changed into a construction of the multilink mechanism. This simulation model is defined as the "multilink model". In addition, the simulation model based on the approximate theory of the organism's propulsion is defined as the "approximate organism model". The thrust force ratio and the swimming speed ratio of the multilink model to the approximate organism model were calculated. The relationships between the two ratios and both the number of links and the ratio wavelength/amplitude were clarified.
