Research Description

Food production have been of great importance due to global climate change and geopolitical risks. On the other hand, agricultural population have been decreasing and aging though agriculture should play a major role for food production in Japan. As well as population decrease and aging, fatal farm accident is also a serious issue in Japanese agriculture. In agriculture, fatality rate is greater than other industries, such as constructions and manufacturers. The reduction of fatal farm accidents is essential to achieve sustainable and safety food production. More than half of fatal farm accidents have been caused by farm machinery. Thus, it is necessary to keep safe during machinery operation.
I have worked on prevention of tractor overturning accident and clarifying accident mechanism. I have conducted physics modeling and numerical simulations based on nonlinear dynamics and clarified operational conditions in which tractor overturning would occur. Based on the abovementioned research, I have developed driving simulator system for farmer safety educations. I also worked at Hitachi research laboratory as a research scientist and conducted research related machinery reliability and data science.
I will conduct research based on physics modeling and statistical modeling to improve farm machinery safety and reliability.
