Crashworthy Post Utilizing Conservation of Linear Momentum and Energy Absorbing Module and Method for Reducing Car Impact using such Crashworthy Post

摘要

The present invention relates to an impact reduction post and a method to reduce impact upon a car crash on a post using the same. According to the present invention, the post assembles and couples a post body and a base member with a fixation member to increase a supporting force against wind load and the like so as to reinforce rollover stability, thus being able to exhibit an excellent safety ensuring performance; transfers linear momentum of the car to the post body when a car collides with the post body, such that impact energy is partially dissipated while the car and the post body move in an integrated state; and allows an impact energy absorption module (EAM) or member of impact energy installed in the base member to be collided and deformed as the post body moves back by a crash, thus dissipating the remaining part of the impact energy of the car. The impact reduction post comprises the base member and the post body vertically erected to be installed on the base member.
