Title:
圧延管表面ドラッグによる運動摩擦力と圧延力を用いた車両衝撃を吸収する方法、及びこれを用いた車両衝撃吸収装置
Document Type and Number:
Japanese Patent JP5315458
Kind Code:
B2
Abstract:
An object of the present invention is to continuously secure a displacement while dynamic kinetic energy of a vehicle is absorbed by a kinetic frictional force and rolling force produced by dragging a surface of a soft rolled tube, and to let an evaluation index of PHD belong to a passenger safety index by slowly maintaining the maximum deceleration applied to the vehicle and passenger, thereby preventing a human in safe against fatal impact. The present invention is configured to reduce the maximum deceleration by 20g or less by a kinetic frictional force of a first dragging kinetic frictional force inducing member at a front end portion of a rolled tube 10, in which dynamic kinetic energy of a vehicle is the highest, significantly reduce the kinetic energy by a second dragging kinetic frictional rolling force inducing member having a kinetic friction coefficient larger than that of the first dragging kinetic frictional force inducing member at an intermediate portion of the rolled tube, and to wholly absorb the remaining kinetic energy by a third dragging kinetic frictional rolling force inducing member installed along a stopper distance.
