Laboratory Introduction (Department of Mechanical Engineering)
A machine can be defined as something that has a shape, can move, can be touched directly, and can be seen, possesses a power source, and performs effective work by performing a predetermined motion. Machines are classified into power transmission machines, production machines, precision machines, fluid machines, transportation machines, construction machines, agricultural machines, computers, etc., and the study of how to create such "things" as machines is called mechanical engineering.
While mechanical engineering encompasses a wide range of academic disciplines, Aoyama Gakuin University is broadly composed of four fields: mechanical materials and mechanics of materials, thermal engineering and fluid engineering, mechanical dynamics and measurement and control, and precision engineering. Each of these fields conducts cutting-edge research.
In your fourth year, you can join a research lab in one of these fields and conduct a fulfilling graduation research project. Prior to this, in your second and third years, there is a course called "lab work," where, if you wish, you can spend a year in a research lab, experimentally verifying the principles and theories you learned in class, experiencing the atmosphere of the lab alongside undergraduate and graduate students, and getting a glimpse into cutting-edge research.
Furthermore, if you enroll in our university's Aoyama Gakuin University school after graduation, you can deepen your graduation research or conduct new research, and you can also conduct research at national research institutions that are affiliated with Aoyama Gakuin University through our collaborative graduate school program.

Solving the mystery of the mechanism hidden in the relationship between "moving objects" and "flow"
When a structure is exposed to a flow of fluid (air, water, etc.) or moves through the fluid at high speed, vibrations and noise can occur due to the surrounding flow. This type of vibration is called flow-induced vibration, and can occur in fluid machinery such as fans and pumps, and in manufacturing lines for highly functional thin films (high-speed conveying and drying processes). (This is the mechanism by which vibrations are generated from flows.) The occurrence of this vibration can cause a decrease in the performance of machinery or a breakdown, so it is necessary to understand the excitation mechanism and take measures to prevent it from occurring.
On the other hand, aquatic organisms such as fish are adept at swimming through the water by using vibrations in reverse. (This is a mechanism that generates currents from vibrations.) Through the course of evolution, such aquatic organisms have acquired an excellent swimming method that skillfully utilizes the vibrations of their fins and the wave motion of their soft bodies, as well as an optimized body shape. Aquatic organism-inspired mechanisms modeled on such "soft movements" are safe even when in close proximity to humans, and have excellent propulsive performance even when there are many obstacles in the water.
In our laboratory, we are investigating the excitation mechanisms of flow-induced vibrations, developing vibration suppression technology and vibration control devices, and researching and developing soft propulsion mechanisms in fluids that utilize vibration and wave motion.
