Abstract

Recently, natural disaster has been occurring all over the world; Hurricane Katrina in Florida, Flooding in Thailand, and Tsunami on 3/11/2011 on north-east coast of Japan are those of significance. Large number of vehicles were submerged in those disaster (for example: 230,000 vehicles in 3/11 disaster). Although several experimental based vehicle submerging had been studied, the theory and mechanical analysis of vehicle submerging have not be seen. We have challenged to make a surrogate test since immediately after 3/11/2011. In this paper, the fundamental theory and mechanism of vehicle submerging is explained by a simulation based mechanical modeling and surrogate test, and it is verified by actual submerging experiments. It is clarified that the size of water passing area is the main cause of vehicle submerging.
