| Outline of Final Research Achievements |
In this research, it was verified that the optimal prestress for giant magnetostrictive material is 8MPa. It also was found that a use of aluminum coil is quite effective from the viewpoint of weight saving though it decreases a produced electric power by 20-30%. We also made comparisons in terms of a magnetic circuit, namely comparisons between a closed circuit and open circuit. We expected that a generator with the former circuit should result in a better performance than that with the latter due to a better magnetic containment effect of the former configuration. However, we did not get a clear evidence endorcing the expectation. It will require further investigation in future.
