    Investigation on the flame characteristics in a PCCI engine using endoscope system with micro-cassegrain

    Diesel engines are most frequently used in vehicles because of their high efficiency and durability. However, nitrogen oxide (NOx) and particulate matter (PM) from diesel engines are became problem. Recently, ...

    Driver propensity characterization for different forward collision warning times

    The forward collision warning system, which warns danger to the driver after sensing possibility of crash in advance, has been actively studied recently. Such systems developed until now give a warning, regard...

    Hydroplaning simulation of a tire in thin water using fem and an estimation method and its application to skid number estimation

    To simulate the hydroplaning of a tire, many analytical studies have been performed using commercial explicit FE (Finite Element) codes such as MSC.DYTRAN and LS-DYNA. However, most previous studies on this su...

    Design methodology to reduce the chest deflection in US NCAP and EURO NCAP tests

    There have not been many studies on the factors that affect chest deflection, although the US NCAP thoracic injury criterion was recently shifted from the 3-msec clip to chest deflection. This study explored t...

    Hydroplaning simulations for tires using FEM, FVM and an asymptotic method

    Hydroplaning tires have been frequently simulated using commercial explicit FEM (Finite Element Method) codes. However, these simulations are slow, and the result of the lift force is so oscillatory that the h...

    Stochastic analysis of the variation in injury numbers of automobile frontal crash tests

    Although automobile crash test data have a comparatively large variation because of the complexity of the tests, only a limited number of crash tests are usually conducted due to monetary and time limitations....
