Embodiment Construction
[0013] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0014] 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 sensor set on the dummy inside the test vehicle starts 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 line be...

The invention discloses an auxiliary centering device for a vehicle columnar crash test, which is used for centering a crash line of a crash column with a runway central line during a columnar crash test. The centering auxiliary device comprises a trough which is internally provided with a trough bottom plane, a first trough wall plane and a second trough wall plane, wherein the first trough wall plane is parallel to the second trough wall plane; the trough bottom plane is perpendicular to the first trough wall plane and the second trough wall plane; the distance between the first trough wall plane and the second trough wall plane is the same as the diameter of the crash column; and a central mark which is aligned to a plumb line during centering is arranged on a first central line on the trough bottom outside the trough with equal distance to the first trough wall plane and to the second trough wall plane. By adopting the auxiliary centering device disclosed by the invention, the crash line of the crash column can be centered with a runway central line rapidly during the columnar crash test, and the auxiliary centering device facilitates the obtaining of an accurate crash zero moment.
Description
technical field [0001] 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 [0002] 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 Zhejiang Provincial Key Laboratory of Automobile Safety Control Technology includes two types of frontal columnar crash test (32km / h) and side columnar crash test (29km / h), which are mainly used to test airbags, side air curtains and car bodies structure a...
