Description

25% offset collision barrier for left side and right side of vehicle

Technical Field

The application relates to the technical field of vehicle collision tests, in particular to a vehicle left and right side 25% offset collision barrier.

Background

Vehicle collisions may be classified into frontal collisions, side collisions, rear-end collisions, crash rolls, and the like. The occurrence rate of the frontal collision accidents is high (accounting for about 40% of the total number of the traffic accidents), and the deformation characteristics of the vehicle and the injury degree of the personnel in the frontal collision are different under different overlapping rates. The 25% offset frontal collision of the safety index of the China insurance automobile is a new working condition for testing the safety of the automobile at home and abroad in recent years, and is used for simulating the safety performance of the automobile when the automobile collides with a trunk, a telegraph pole and other vehicles and is in an off-position collision condition.

The existing 25% offset collision barrier is installed on a rigid wall, and the whole length of the barrier is required to be longer so as to ensure the distance between the barrier and the rigid wall. Recently, the new passenger side front face 25% offset (also called as "right side small offset") is added in the 2020 version of the China insurance automotive safety index code. However, the conventional crash barrier can only collide with the barrier on the driver side of the vehicle, but cannot collide with the barrier on the passenger side.
