Outline of Final Research Achievements

Newly developed the hoop type VIM generator system is tested in the circular tank.　This is a pendulum type pillar connected in the bottom. VIM swinging motion of the pillar in the low speed current makes circular motion of the hoop pendulum and motion generate electricity. Small sized model is prepared for circular channel test and also developed a data logger system. Microchip PIC18F2553 core data logger system acquired 8 channel 20Hz 12bit A/D sampling data. From the circular water channel test, maximum efficiency layout of the pillar is shown and electricity performance.
Analytical solution of the hoop motion is studied numerically. Newly developed the equation of the pendulum motion, this is composed dual-pendulum system, is large amplitude under the nonlinear strong restoring gravitational force. From numerical analysis, chaos phenomena and region is shown. Controlling this chaos motion of the pendulum, there might be higher efficiency performance of this system.
