Shock absorption method by absorbing the kinetic energy of the vehicle by the kinetic frictional force by dragging by the kinetic frictional induction bolt of the drag motion friction rolling force induction of 20g or less while maintaining the maximum deceleration speed and shock absorption using the same Relates to a device. This is to ensure that the rider's life is not fatal due to the maximum deceleration.
- the motion friction induction bolt of the soft rolling tube and the drag motion friction rolling force guide of the hard material harmonize with each other to generate kinetic friction and rolling force, and the conventional shock absorbing method with the rear barrier fixed.
- the conventional shock absorbing method in that it moves along the stopper length of the guide rail and the kinetic frictional force induced rolling tube is a new shock absorbing method.
- the vehicle shock absorber of the present invention is installed at the front of the inlet of the overpass or the supporting piers of the overpass. It is possible to apply the same type of shock absorber to the roadside guardrail of a general road or highway.
- the shock absorber installed on the road protects human life by gently maintaining the maximum deceleration (Ridedown Deceleration: -g) received by the vehicle and occupant while continuously absorbing the displacement while absorbing the dynamic kinetic energy of the vehicle. Facilities for.
- the shock absorption of the shock absorbing facility is a mechanism that absorbs the shock as the speed V 1 of the vehicle collides with the shock absorbing facility and the speed V 1 becomes zero.
- the shorter the time ⁇ t before the speed Vo of the vehicle becomes the speed V 1 0 after the collision, the shorter the displacement distance with respect to the impact amount. This is because the displacement distance is a physical quantity defined by the product of velocity and time.

- the shock absorbing device of Korean Patent No. 0765954 does not have a stopper length (S) at the rear end thereof, which may cause secondary accidents due to the remaining amount of kinetic energy.
- the reaction method is a method of absorbing shock by the compression force of the spring.
- the displacement length is inevitably limited, the displacement length is shorter than the method by the bending deformation, so the maximum deceleration rate is large, which may cause the PHD, which is the safety index of the occupant, to exceed the reference value.
- the compressed spring acts as a repulsive force that reverses the vehicle's rushing direction while retaining the absorbed impact energy. This is a result of only changing the direction in the opposite direction of the vehicle rushing direction has a problem that the secondary accident of the occupant is caused to be fatal to the safety of the occupant.
