Abstract

The invention relates to a stiffness test bench device of debugging engine hood used in the automobile collision test and use method thereof, which solves the problem that the traditional automobile part collision tester is not suitable for finishing the collision test of the engine hood; a hood lock connection column and a hood hinge connection column are arranged on the base of the bench; the hood hinge connection column is in the fixed height; a T-shaped fixing guide rail is fixed on the base of the bench; a buffer block connection column moving along the fixing guide rail is arranged on the fixing guide rail; a movable guide rail is arranged on the base of the bench; the hood hinge connection column is movably arranged on the movable guide rail; and the buffer block connection column and the hood lock connection column are in the structure with variable height. The installation angle of the engine hood in the normal state is simulated via the hood hinge connection column, the buffer block connection column and the hood lock connection column; the tested results are in accordance with the actual situations; the stiffness of the engine hood is really reflected; and the stiffness test bench device of debugging engine hood is applicable for the engine hoods in the different automobile types.

Description

technical field [0001] The invention belongs to the field of vehicle testing, in particular to an adjustable engine hood rigidity test stand device used in a vehicle collision test and a method for using the same. Background technique [0002] In order to improve the safety performance of automobiles, the automobile crash test is an indispensable means of verification, because most of the accidents are collisions, and the test results basically reflect the safety degree of the automobile to the occupants and pedestrians. The European New Car Safety Evaluation Association's crash test has two basic items, namely frontal and side impact. China's C-NCAP vehicle crash test includes frontal collision, side collision and rear collision. Currently, China only adopts 100% frontal full-contact collision test. [0003] In the collision test between a car and a structure, it is necessary to accelerate the car to the set speed and make it collide with the structure. Because the car cra...
