Recently, the reduction in size and weight of machine products is given as one approach of the industrial world to energy problems. However, the vibration and noise problem at high frequency shows a tendency to occur because of the thin plate structure. The following contents are examined using energy analysis methods.
i) Identification of vibration source and noise source
ii) Reduction of vibration and noise
iii) Expansion to diagnostic technology as to vibration and noise

- The purpose of this research is development of robots which is used in various fields and applied for human society. For example, exploration of ocean resources are expected, while operations on underwater are dangerous for human. Therefore, AUVs (Autonomous Underwater Vehicles) are needed on behalf of human worker. To apply robots for such projects, robust hardware, sensing system and adaptive control system are needed. Additionally, in order to apply robots in crowded area,not only navigation system but safety of human should be considered.

Ships have to move a large volume of cargo to desired destinations cheaply and on time. In order to achieve projected objectives, the target speed has to be attained by smaller engines.
Put another way, the improvement of propulsive performance is desired.
We study low-resistance ship forms and high performance propellers theoretically and experimentally.
Experiments are conducted in the towing tank (L×B×D=60m ×4m×2.3m) and the small circulating channel at NIAS.

In order to plan and design various kinds of offshore structures, it is necessary to analyze and evaluate the hydrodynamic performance of those offshore structures. We study a method to predict, theoretically and experimentally, the response character- istics of offshore structures with reference to the effect of mooring system in waves.
Moreover, a new type of offshore structure with excellent performance is investigated by use of the above method, and its potential for realization is evaluated.

- The effects of several parameters related to fatigue strength, i.e. material, mechanical, shape and environmental factors, must be understood quantitatively in order to estimate the fatigue strength of welded structures accurately and to develop new materials or components with excellent resistance to fatigue failure. To accomplish this, we carry out investigations to establish a method to evaluate fatigue strength experimentally and theoretically.
