Embodiment Construction
[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.
[0031] Furthermore, the drawings are merely schematic illustrations of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities. These functi...

The invention relates to the technical field of vehicle safety testing, and provides a B-pillar collision test method. The method comprises the steps of: installing a B-pillar assembly to a load-bearing wall body through a cross beam fixing tool, arranging a force measuring tool between the cross beam fixing tool and the load-bearing wall body, and arranging a high-speed camera on the load-bearingwall body; enabling a collision trolley provided with an acceleration sensor to collide with the B-pillar assembly at an impact position in a first direction, letting the acceleration sensor collectthe acceleration of the collision trolley, enabling the high-speed camera to collect the deformation displacement of the impact position of the B-pillar assembly, and letting the force measuring toolcollect the bearing stress of the B-pillar assembly; and according to the acceleration, the deformation displacement and the bearing stress, acquiring the collision performance of the B-pillar assembly. The whole vehicle side impact test is simulated through the impact test of the B-pillar assembly, the test is simple and convenient, the period is short, the test can be repeated for multiple times, the reliability is high, and the cost is saved.
Description
technical field [0001] The invention relates to the technical field of vehicle safety testing, in particular to a B-pillar collision test method. Background technique [0002] Before the vehicle is put into use, safety tests are required. One of the important safety tests is the side impact test of the whole vehicle. By colliding with the B-pillar of the body, the side impact performance of the B-pillar of the body is analyzed, and then the safety of the vehicle is judged. [0003] In the prior art, the vehicle side impact test is carried out with the whole vehicle, which will bring the following problems: the process of the vehicle side impact test is cumbersome and the test period is long; after the vehicle side impact test is completed, the vehicle cannot be repeated due to collision deformation In addition, the vehicle side impact test must be completed by a professional organization with relevant qualifications, and the cost is relatively high. [0004] It should be no...
