Embodiment Construction

[0014] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] figure 1 It is a schematic diagram of the device for the vehicle columnar impact test of the present invention. Such as figure 1 As shown, a collision line 201 is provided on the cylinder surface of the collision cylinder 20 . The trigger switch 30 is strip-shaped, and a sensitive part 301 is arranged on it. Stick the trigger switch 30 on the collision column 20 so that the sensitive part 301 basically coincides with the collision line 201 . At the moment of the collision (that is, the zero moment of the collision), the test vehicle touches the trigger switch due to the collision, and the sensors installed on the dummy inside the test vehicle start to collect data. In order to ensure the accuracy of the test data, a relatively accurate zero moment of collision is required. This requires that the collision point or collision l...

Abstract

The invention discloses a centering auxiliary device for a vehicle pole collision test for centering a collision line of a collision pole and a runway centerline in the pole collision test. The centering auxiliary device comprises a clamping groove; the clamping groove is internally provided with a groove bottom plane, a first groove wall plane and a second groove wall plane; the first groove wall plane is parallel with the second groove wall plane; the groove bottom plane is vertical to the first groove wall plane and the second groove wall plane; the distance between the first groove wall plane and the second groove wall plane is consistent with the diameter of the collision pole; and a first middle line, equidistantly from the first groove wall plane and the second groove wall plane, on the outer groove bottom of the clamping groove is provided with a center marker aligned with a plumb line in the case of centering. The centering auxiliary device of the invention can quickly center the collision line of the collision pole and the runway centerline in the pole collision test. Also, an accurate collision zero hour can be obtained.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of September 6, 2012, the application number of 201210326708.7, and the title of "Centering Auxiliary Device for Vehicle Columnar Collision Test". technical field [0002] The invention relates to the field of automobile passive safety testing, and more specifically relates to a centering auxiliary device for a vehicle column collision test. Background technique [0003] The main direction of the development of modern automobile technology is safety, environmental protection and energy saving, among which, the safety performance of automobile driving is particularly important. Automobile crash test is currently the most basic and effective method to comprehensively evaluate automobile safety performance. The pillar crash test is one of four crash types examined in the adult protection section of E‐NCAP (European New Car Assessment Program). The columnar crash test of...
