The lab studies and designs the structural mechanical properties of mechanical materials and mechanical systems.

AboutAbout the lab
Measuring and designing the mechanical properties of structures.
Matsubara Lab studies mechanical materials and the mechanical systems made by combining them.
The lab aims to improve the efficiency and reliability of machines that support modern society, such as transportation systems and heavy electrical equipment.
To this end, it investigates the mechanisms that determine the structural mechanical properties and studies methods for designing them.
Its main research areas are tire vibration, measurement by image processing, and evaluation of the physical properties of materials.
Key terms
- Structural mechanical properties
- The properties that describe how much an object deforms and how it vibrates when subjected to a force
- Downsampling
- Processing that thins out finely sampled signals or images to convert them into coarser data
- X-ray CT
- A measurement method that uses X-rays to image the three-dimensional internal structure of an object without destroying it

ResearchResearch themes
Matsubara Lab aims to achieve higher functionality and greater reliability. It investigates the mechanisms that determine structural mechanical properties and studies methods for designing them. Its research rests on three pillars: the dynamic behavior of tires, three-dimensional displacement measurement by image processing, and evaluation of the physical properties of polymer materials.
*Illustrative imageDynamic behavior of tires
Tire models are one of the most important elements in simulating vehicle noise, vibration, ride comfort, and durability. The lab studies modeling and measurement techniques for understanding the dynamic behavior of tires, balancing computational accuracy with efficiency.
*Illustrative imageMeasurement by image processing
The lab develops methods for measuring three-dimensional displacement using image processing and downsampling techniques. Obtaining clear images is just as important as tracking feature points accurately, so the lab also studies lighting conditions.
*Illustrative imageEvaluation of material properties
Polymers are important structural materials used in sealing materials, tires, vibration-damping materials, and actuators. Their mechanical properties depend on their internal microstructure, so the lab investigates the relationship between the two using measurements such as dynamic X-ray CT.
