The lab explores the mechanisms of vibration and waves to create new technologies.
AboutAbout the lab
Unraveling vibration to create new technologies.
The Mechanical Dynamics Lab works to elucidate phenomena related to the motion of machines, such as vibration and waves, and to develop new technologies that use them.
With the SDGs in view, the lab works on vibration energy harvesting using new mechanisms and on vibration control that reduces energy costs.
Using a new diagnostic technique based on ultrasonic waves, the lab aims to establish the safety and reliability of machines.
The targets are not limited to mechanical structures but also include living bodies and food, and the lab actively engages in joint research with companies and contract research.
Key terms
- Vibration energy harvesting
- Generating electricity from the vibration of machines or structures.
- Ultrasonic modulation
- A phenomenon in which the frequency of ultrasonic waves passing through a contact interface inside an object changes depending on the state of that interface.
- Wavelet transform
- One of the techniques for analyzing signals such as vibration.

ResearchResearch themes
The lab elucidates phenomena related to the motion of machines, such as vibration and waves, and develops new technologies that use them. Its targets are not limited to mechanical structures but also include living bodies and food.
*Illustrative imageVibration systems that automatically follow the vibration frequency
The lab studies vibration systems that automatically follow the frequency of an applied vibration, focusing on natural frequency, nonlinear vibration systems, and dynamic vibration absorbers. It also works on vibration energy harvesting using new mechanisms.
*Illustrative imageUltrasonic diagnosis of machine abnormalities
Using ultrasonic modulation, a phenomenon in which the frequency of ultrasonic waves passing through a contact interface inside an object changes, the lab aims to detect cracks and delamination from their early signs. It also works on diagnosing loose bolts.
*Illustrative imageEfficient evaluation of car body vibration
The lab studies a method to efficiently evaluate the vibration of car bodies, which are made of a frame and panels, by separating it into overall deformation and local deformation. Vibration modes obtained by the finite element method are decomposed with a three-dimensional wavelet transform.
*Illustrative imageVibration diagnosis using vibration data
Using easily measured acceleration, the lab is devising vibration diagnosis methods that allow a high degree of freedom in measurement position and remain robust to noise while maintaining sensitivity. It uses various signal analysis techniques, such as the wavelet transform, and confirms their effectiveness through experiments.
