detailed description

Fig. 1 discloses a schematic layout of an airbag abuse test site according to an embodiment of the present invention. As shown in FIG. 1 , the airbag abuse test site includes: an acceleration zone 102 , a test module arrangement zone 104 and a buffer zone 106 .

The vehicle accelerates in the acceleration zone 102, which is trumpet-shaped, with a long middle zone and gradually shortened lengths on both sides. In the illustrated embodiment, the central axis of the acceleration zone 102 has the longest length, and the two sides are in the shape of a flared mouth, and the lengths of the two sides of the acceleration zone 102 are gradually shortened. In this way, the vehicle accelerates at the central axis position of the acceleration zone, and can obtain the longest acceleration time, correspondingly, has the highest speed. On both sides of the acceleration zone 102, the acceleration distance is gradually shortened, and correspondingly, the speed obtained by the vehicle is also gradually reduced. In the illustrated embodiment, a branch acceleration road 121 is formed in the acceleration area 102 , and the branch acceleration road 121 has a relatively long distance, and a vehicle traveling in the branch acceleration road can obtain a higher speed. The exit of branch accelerating track 121 can be positioned at the edge of accelerating zone 102, and branch accelerating track 121 can make the arrangement of accelerating zone 102 more flexible, and when necessary, can also obtain higher speed at the edge position of accelerating zone 102 through branch accelerating track 121 speed. In one embodiment, the acceleration zone 102 is an asphalt road. Since not all test modules require a higher test vehicle speed, the trumpet-shaped acceleration zone 102 can greatly save the occupied area compared with the traditional square acceleration zone.

The test module arrangement area 104 is located at the rear of the acceleration area, and several test modules are arranged in the test module arrangement area 104, and the vehicle passes through the test modules after passing through the acceleration area 102 and accelerating. The vehicle accelerates to the test vehicle speed required by the corresponding test module in the acceleration zone 102, and then drives through the corresponding test module. Since the acceleration zone 102 has different lengths, vehicles passing through different locations of the acceleration zone 102 are accelerated to different speeds. The speed near the central axis is the highest, and the speed gradually decreases to the sides. Correspondingly, the several test modules are generally arranged from the middle of the test module arrangement area 104 to both sides according to the test vehicle speed from high to low. On the whole, the test module with the highest test vehicle speed is arranged at the central axis of the test module arrangement area 104 , and the test vehicle speed of the test module decreases gradually from the central axis to both sides. It should be noted that due to the limitation of the area of the test module arrangement area 104 and the limitation of the long-distance area of the acceleration area 102, when the number of test modules with a high test vehicle speed is large, the position of the axis in the test module arrangement area 104 may be insufficient In order to arrange all the test modules with higher test vehicle speed. At this time, the aforementioned branch acceleration track 121 can be used, and the test modules with higher test vehicle speeds can also be arranged in alignment with the branch acceleration track 121 , and the vehicles accelerating through the branch acceleration track 121 can also have a higher speed. The branch acceleration road 121 enables the vehicle to be accelerated to a high speed at more positions.

The buffer zone 106 is located behind the test module arrangement area 104, and the vehicle decelerates in the buffer zone until it stops. The buffer zone 106 is located behind the test module arrangement area 104. After the vehicle passed the test module arrangement area 104, the airbag abuse test has been completed. After entering the buffer zone 106, it needs to slow down and stop as soon as possible. In one embodiment, the buffer zone 106 is a milled asphalt gravel pavement,

The test modules arranged in the test module arrangement area 104 are concrete modules. In one embodiment, the following test modules are arranged in the test module layout area 104: gravel road 201, Belgian stone road 202, railroad track 203, concave jump road 204, beam 205, cross ditch road 206, Hump Road 207, Model Beast 208, Curb 209, Boss 210, and Cobblestone Pile 211.

Several test modules are divided into high-speed module, medium-high speed module, medium-speed module, medium-low speed module and low-speed module according to the test speed. Overall, the high-speed module is arranged on the central axis of the test module layout area, and the medium-high speed module, medium-speed module, medium-low speed module and low-speed module are respectively arranged on both sides of the central axis. As mentioned above, when there are many high-speed modules or medium-high-speed modules, the high-speed modules or medium-high-speed modules will also be arranged at the positions corresponding to the branch acceleration lanes. In one embodiment, the module types are divided according to the test vehicle speed as follows: the test vehicle speed of the high-speed module is 80-100km/h; the test vehicle speed of the medium-high speed module is 70-80km/h; the test vehicle speed of the medium-speed module is 60-70km/h h; the test speed of the medium and low speed module is 40-50km/h; the test speed of the low speed module is below 40km/h.

The commonly used test modules are introduced in detail below.

In one embodiment, the Belgian stone road 202 uses Belgian stones as the road surface, and the entire length is 110m. Due to the longer length of the Belgian stone road 202, compared with other modules, the starting position is more forward and occupies a longer area. According to the overall design, the Belgian stone road as a medium and high-speed module should be arranged in the area near the central axis in the test module layout area 104, but considering the long length of the Belgian stone road 202, it is easy to interfere with other module tests, for example, If the vehicle loses control during the test of other modules, the vehicle will inevitably impact the adjacent Belgian stone road, thereby reducing the service life of the module. Therefore, in the embodiment shown in FIG. 1 , the Belgian stone road 202 is arranged at one side edge of the test module arrangement area 104 . Since the Belgian stone road 202 is a medium-high speed module and requires a higher test vehicle speed, the acceleration zone 102 is equipped with a branch acceleration lane 121 for it. The Belgian stone road 202 is aligned with the exit of the branch acceleration road 121, and the test of the Belgian stone road 202 is carried out after the vehicle accelerates to a medium-high speed in the branch acceleration road 121.

Railroad 203 is a medium-speed module, and the test speed is 60-70km/h. The railway track 203 simulates the inclined railway track mouth, and when the test vehicles pass through this module at the required test speed, tire blowouts will often occur. Because tire blowout is easy during railroad test, therefore in the embodiment shown in Fig. 1, railroad 203 is placed in the position near the edge of test module layout area 104, once blowout occurs, the guardrail on the edge of the site can make the uncontrolled test The vehicle stops as soon as possible, reducing the occurrence of safety accidents and avoiding the impact on the side modules, which can facilitate the maintenance of the test vehicle and subsequent maintenance of other test modules.

In the illustrated embodiment, the transverse trench 206 is arranged behind the crossbeam 205 , and is also arranged near the middle of the test module arrangement area 104 . The transverse ditch road 206 is arranged at the rear of the crossbeam 205 because the test vehicle speeds of these two test modules are similar, both are medium-speed modules, and the test vehicle speed is 60-70km/h (the crossbeam 205 is usually set as a medium-speed module). In addition, the test modules are small in size and short in length, and can be arranged front and back to save the site area. When the crossbeam 205 needs to be tested, the transverse ditch road 206 is covered with a cover plate to form a straight road surface, and then the crossbeam 205 arranged in front of it is tested. When the horizontal ditch road 206 needs to be tested, the cover plate of the horizontal ditch road 206 is removed, and the iron plate and the cross beam of the cross beam 205 are disassembled simultaneously, and the horizontal ditch road 206 is tested. The direction indicated by the arrow in Fig. 6a is the driving direction of the vehicle.
