Description
Technical Field
The invention relates to a test system for simulating tire burst, and belongs to the field of automobile safety.
Background
Along with the high-speed development of automobiles, the potential risks of traffic accidents accompanying the automobiles are increasingly serious, and particularly, along with the improvement of the road grade, the automobiles are also gradually accelerated. According to the relevant statistical data, 10% of traffic accidents on the expressway are caused by tire faults, and one tire burst item accounts for more than 70% of the total accidents caused by tire faults. Therefore, the study of the tire burst phenomenon of high-speed running vehicles and the prevention thereof are becoming more and more difficult problems for researchers in the automobile industry. Therefore, it is necessary to develop a test system capable of simulating a flat tire.
At present, most of tire burst simulation test devices achieve tire burst by adopting modes of deflating or installing explosive substances and the like, the modes can really achieve the purpose of simulating tire burst, but the simulation is only the general tire burst condition, and the actual tire burst condition similar to that of a sharp object scratching the tire cannot be simulated. In real life, a lot of tires are blown out because the tires are contacted by sharp objects during the running process of a vehicle, so that the structure is damaged, and the tires are blown out. Moreover, explosive substances adopted by partial tire burst simulation have potential safety problems in the transportation, storage and installation processes, and are not beneficial to carrying out a large number of tests.
For example, the invention patent application with the application number of CN201810724829, which is named as a novel tire burst simulation deflation device, only simply deflates a tire to simulate a burst, thereby carrying out various researches. In real life, however, the tire burst in some cases is caused by the fact that the tire is scratched by a sharp object when rolling on a road surface, and the tire burst simulation in the more practical cases is difficult to realize by the traditional deflation method. The tire cutting device provided by the invention is used for cutting the tire, so that the tire burst simulation caused by the fact that the tire is scratched by a sharp object when the tire rolls on a road surface is realized. The tire burst simulation caused by cutting is closer to the reality, so that the experimental result obtained by the next experiment is more accurate and is closer to the reality.

The position of the swivel mount 20 is set at the position of the base 11, which is deviated to the left from the midpoint, in order to make the distance between the swivel mount 20 and the first hydraulic cylinder 9 smaller than the distance between the swivel mount 20 and the blade 8, and then, by using the lever principle, under the condition that the rotation angles are equal, the shorter output stroke of the first hydraulic cylinder 9 can be amplified, so that the blade 8 performs the rotation motion with a larger radius. The arrangement can select the first hydraulic cylinder 9 with low stroke or small size under the condition that the rotating arc length of the blade 8 is not changed, so that the whole occupied space of the device is saved.
The output shaft of the motor 1 is connected with the first end of the first shaft 2 through the coupler, the first shaft 2 is fixed in a through hole in the second shaft 5 through the bearing 3, a threaded hole is formed in the center of the end portion of the first shaft 2, the blade 8 is fixed at the end portion of the first shaft 2 through the bolt 6 and the gasket 7, and different tests simulating tire burst actual conditions are adapted by replacing the blade 8.
