Abstract
The utility model provides a rigid barrier for an automobile crash test. The rigid barrier for the automobile crash test is characterized by comprising a crash wall and a transitional wall which are sequentially arranged in the crash direction of an automobile body, wherein the crash wall and the transitional wall are laminated and the wall surfaces of both the crash wall and the transitional wall are in a vertical direction; the front side surface, facing to the automobile body, of the crash wall and the crush direction of the automobile body form an included angle of 80 degrees; and the thinnest part of the crash wall is in smooth serial connection with a turning corner of the transitional wall. According to the technical scheme, during a low-speed crash test of the automobile, the automobile runs at a set speed and the front end of the automobile body collides with a slope structure on the front side of the rigid barrier so as to test the safety during the low-speed crash of the automobile; and the rigid barrier enhances the test development capability of a crash safety test laboratory, can meet requirements on the low-speed crash test of the automobile, and provides a test support for automobile safety development of a company.
Description
Technical field
The utility model relates to the automobile product technical field of measurement and test, specifically relates to a kind of rigidity obstacle that is used for vehicle impact testing.
Background technology
After the automobile generation low speed collision accident, the vehicle loss that accident causes is often born by insurance company, so insurance company must carry out the insurance rating assessment to vehicle.At present, European various countries are incomplete same to the car insurance ranking method, but mainly adopt head-on crash, the afterbody impact test of RCAR (Research Council for Automobile Repairs) to carry out the grading of vehicle low speed collision performance.The security performance of automobile more and more came into one's own in recent years, and the automobile low speed collision has become the development experiments that main engine plants extensively carry out.For the obstacle of collision usefulness, the test order of RCAR has only been carried out simple requirement to the collision obstacle, does not have unified design standards.Be meeting the market requirement,, be badly in need of the test that a kind of obstacle device of exploitation is used for the head-on crash of car load according to the automotive safety development strategy.
Summary of the invention
The purpose of the utility model provides a kind of rigidity obstacle that is used for vehicle impact testing.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of rigidity obstacle that is used for vehicle impact testing; It is characterized in that: described rigidity obstacle comprises successively along impact walls of arranging on the car body collision direction and transition wall; Described impact walls and transition wall arranged stacked and wall are positioned at the plummet direction, and its leading flank and car body collision direction towards car body of said impact walls is 80 ° of angles, and its thickness thinnest part of said impact walls is connected with smooth the postponing in the turning of transition wall.
According to technique scheme: automobile is when carrying out the low speed collision experiment, and automobile goes with setting speed, and the domatic structure of this obstacle front side of car body front end and rigidity is collided, with the low speed collision safety-type of testing automobile.This rigidity obstacle has promoted collision safety laboratory test development ability, satisfies the needs that are used for the test of automobile low speed collision, to company's vehicle security development test support is provided.

Embodiment
A kind of rigidity obstacle that is used for vehicle impact testing; Like Fig. 1,2, shown in 3: described rigidity obstacle comprises successively along impact walls of arranging on the car body collision direction 10 and transition wall 20; Described impact walls 10 is positioned at the plummet direction with transition wall 20 arranged stacked and wall; Said impact walls 10 its leading flank and car body collision directions towards car body are 80 ° of angles, and said impact walls 10 its thickness thinnest parts are connected with turning 21 smooth the postponing of transition wall 20.Automobile is when carrying out the low speed collision experiment; The collision width of rigidity obstacle moved to adjust to be 40% of body of a motor car width; State when demonstrating actual bumping with this; Be that automobile goes with setting speed, the domatic structure of its front end and this obstacle front side of this rigidity is collided, with the low speed collision safety-type of testing automobile.This rigidity obstacle has promoted collision safety laboratory test development ability, satisfies the needs that are used for the test of automobile low speed collision, to company's vehicle security development test support is provided.
Described turning 21 its radiuses are 150mm.This size is come out to most of vehicle size design, and it is applied widely, can test the vehicle of various sizes.
Connect and the structure that is welded as a whole through bolt between said impact walls 10 and the transition wall 20.Thereby increase its strength of joint, prolong the collision experiment number of times that it can carry.
Described transition wall 20 trailing flanks are fixing impact face 30; Transition wall 20 is used for fixing the stop sleeve 31 that is connected with fixedly being provided with between the impact face 30; Unthreaded hole 32 for playing the guiding role in the middle of the described stop sleeve 31; Be provided with bolt hole 33 on every side, the plate face of described fixedly impact face 30 and the wall of transition wall 20 are arranged in parallel.For the longitudinal size that guarantees impact walls 10 and transition wall 20 enough big; Make vehicle not can with collision wall generation secondary collision; This impact walls 10 and transition wall 20 are connected with fixing impact face 30; It tests shared fixing impact face 30 devices with 40% offset collision at a high speed, saves material, has reduced unnecessary waste.Wherein stop sleeve 31 can play good fixed connection effect, and unthreaded hole 32 plays the effect that guiding is installed, and stop sleeve 31 is aimed at the fixing installation site of impact face 30, is beneficial to twisting admittedly of nut, and always increases integrally-built intensity.
Described stop sleeve 31 has 6, and it evenly is laid in impact walls 20 and fixedly between the impact face 30, described bolt hole 33 has 8.It mainly also is to play the effect that increases its strength of joint.
Described fixedly impact face 30 is installed on the collision wall 40, and said collision wall 40 laterally arranges with fixing impact face 30, described fixedly impact face 30 transition wall 20 with collide between the wall 40.With driving whole obstacle is installed on the fixedly impact face 30 of collision wall 40.According to overall width, the adjustment position can make an experiment.Easy for installation, safe, quick, improved work efficiency greatly.Can satisfy test standard, can carry out smoothly by warranty test again.
Described collision wall 40 is provided with the fixedly governor motion of impact face 30 relative positions of scalable.So just can be according to the automobile of different size, regulate its relative position that is fixed in the rigidity obstacle on the fixing impact face 30 through governor motion, promptly can carry out the adjusting of position up and down, to satisfy testing requirement to it.
