Testing device and testing method for simulating tire burst

Abstract

The invention discloses a testing device for simulating tire burst. The testing device comprises a cylinder body, a cover body, a mounting disc and an acquisition controller, wherein a plurality of first through holes are formed in the cylinder body; the cover body is arranged above the cylinder body, a pressure maintaining space is formed between the cover body and the cylinder body, and the cover body can move up and down relative to the cylinder body so as to seal or open the pressure maintaining space; the mounting disc is used for fixing the cylinder body and a driving cylinder; a plurality of through grooves are formed in the mounting disc in the radius direction of the mounting disc and can randomly form at least two through groove groups for adapting to tires of different specifications; and the acquisition controller is arranged on the driving cylinder and is used for controlling the extension and retraction of the driving cylinder and acquiring tire pressure parameters. According to the testing device, the plurality of first through holes are formed in the cylinder body to connect the pressure maintaining space with an inner cavity of the tire, and when the pressure maintaining space is opened for pressure relief, the plurality of first through holes act simultaneously to instantaneously and sharply reduce the air pressure of the inner cavity of the tire, so that thepressure relief of the inner cavity of the tire is quicker, and the simulated tire burst process is more real.

Description

technical field

[0001] The invention relates to the technical field of testing auto parts, in particular to a testing device and testing method for simulating tire bursting. Background technique

[0002] With the rapid development of modern transportation, the number of cars and the number of new cars are increasing year by year, and the pressure on roads is also increasing. For example, on expressways, the density of vehicles is getting higher and higher, especially during holidays. Vehicles driving on the expressway are in a relatively closed environment with no other road users except cars. When danger occurs, except for abnormal driving caused by subjective factors such as fatigue driving and drunk driving, objectively it is the easiest The cause of serious car accidents is blown tires.

[0003] Relevant statistics show that about 10% of the traffic accidents on the expressway are caused by tire failure, and one of them just accounts for more than 70% of the total amoun...
