Main research topics
Vibrations occur everywhere around us; they can be harmful to objects and people. For example, vibrations of machines and machine elements can cause inaccurate machining of products, noise, and damage. In such cases, these vibrations need to be reduced. In addition, vibrations of structures during large earthquakes can cause catastrophes. Therefore, techniques for condition monitoring and abnormality diagnosis are important in the case of structural vibrations.
I am conducting research on the modeling, analysis, and design of human-made objects such as machines, equipment, and structures, with the aim that these technologies will contribute to achieving Sustainable Development Goals (SDGs) 9, 11, and 12. Specifically, I am researching methods for identifying the dynamic characteristics (vibration characteristics) of objects based on their dynamic responses, analytical methods for design modification based on these identified vibration characteristics, and methods for condition monitoring and error diagnosis based on the identified vibration characteristics.
Recently, I have also been interested in the movement of the human body; In April 2024, I will begin my research for contributing toward achieving SDG 3, “Good Health and Well-Being.” Specifically, I will work on developing a vibration suppression device (active dynamic vibration absorber) for people with essential tremor disorder (hand and finger vibrations), which can be used in cases where precision work by humans is required, such as microscopic surgeries. For the control method, I will consider the reverse application of techniques that promote vibrations of objects; furthermore, I will incorporate machine learning techniques. I will establish a method to suppress hand and finger vibrations and develop a technology that will be appreciated by society.
