1. Vibration Control, Noise Control, Shock Control of Space Structures

We have developed vibration control, acoustic control, and shock control for space structures such as space stations, lunar bases, and artificial satellites. In space, sufficient of power supply is not expected. Thus, an innovative method is required to suppress structural vibration using a self-powered control device. Our laboratory focuses on a truss structure that forms a structural member for next-generation space stations. We have installed a truss structure in our laboratory, which is employed for proof experiments.

2. Energy-Harvesting Using Smart Structures

We cannot solely rely on solar power generation on the moon because night time occurs for up to 14 days. Therefore, energy harvesting from vibration sources should be explored. We are developing an energy harvester that is utilized not only in space structures but also vehicles such as airplanes and automobiles.

3. Experiments for Space-Debris Impacts

The impact of space debris and meteorites is a serious issue for space structures. We have implemented measures to mitigate hypervelocity impact in collaboration with JAXA. We are investigating the use of a conductive tether system for debris removal.

4. Aeroservoelastic Modeling for Variable Morphing Wings

Next-generation aircraft is expected to have a variable wing (morphing wing) to achieve fuel efficiency and compactness. We integrated three fields (fluid, structure, and control) to establish a coupling model for variable wings.

5. Flexible Multibody Dynamics for Aerospace Structures

For future aerospace structures, an innovative structural analysis is necessary, which differs from conventional frameworks. We conduct pioneering research for future space development.
