A test device and test method for simulating tire burst

Abstract

The invention discloses a test device for simulating tire bursting, comprising: a cylinder body, which is provided with a plurality of first through holes; a cover body, arranged above the cylinder body, and the cover body and the cylinder body There is a pressure-holding space between the bodies, and the cover can move up and down relative to the cylinder to seal or open the pressure-holding space; a mounting plate is used to fix the cylinder and drive the cylinder; the mounting plate A plurality of through grooves are opened along its radial direction, and a plurality of said through grooves can be arbitrarily formed into at least two groups of through grooves for adapting tires of different specifications; The expansion and contraction of the cylinder and the collection of tire pressure parameters. In this application, a plurality of first through holes are set on the cylinder to connect the pressure holding space and the inner cavity of the tire. The air pressure of the tire cavity makes the tire inner cavity depressurize more quickly, so that the simulated tire blowout process is more realistic.

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...
