In recent years, trimarans have been used in high-speed transport and warships, but studies of them made little progress. We designed a trimaran model it to perform water-entry experiment find way reduce the slamming pressure. The process entering water was divided into several steps, different theoretical models were for each step, together with their force analysis. Relying on our experimenta...

in this research, numerical simulation of a symmetric impact of a 2-d wedge, considering dynamic equations in two-phase flow is taken into account. the two-phase flow around the wedge is solved based on finite volume method and volume of fluid (vof) scheme. the dynamic mesh model is used to simulate dynamic motion of the wedge, thereby the effects of different dynamic meshes in both structured ...

In high income countries, jumping and diving into water are a small but persistent cause of death serious injury especially among male youth young adults. Although entries maintain media profile, little is known about what entry competencies underlying safety knowledge bring to this practice. Undergraduates enrolled in aquatics (N= 76) completed survey before attempting 7 tasks. While attitudes...

This paper details the study on the changes in riding behaviour, such as changes in speed as well as the brake force and throttle force applied, when motorcyclists ride over a curve section road using an instrumented motorcycle. In this study, an instrumented motorcycle equipped with various types of sensors, on-board cameras, and data loggers, was developed in order to collect the riding data ...
