Automobile tire burst simulation experiment device

Abstract

The invention discloses an automobile tire burst simulation experiment device. The automobile tire burst simulation experiment device is fixed on a rim provided with an automobile tire. The automobiletire burst simulation experiment device comprises a pre-tightening trigger device, a withdrawing device, a storage battery and a controller. According to the tire burst simulation experiment device,two sets of roller screw sliding rails are driven by two driving motors correspondingly to drive a puncture device to be far away from and close to the tire so as to realize tire burst simulation andrapid deflation of the tire, and the tire burst simulation experiment device has the characteristics of being rapid to install, low in use cost, high in universality and adjustable in speed; the device can be applied to tire burst experiments of various vehicle types under different vehicle speed road conditions, the structure is simple, the simulation control precision is high, and subsequent experiments of vehicles are not influenced after tire burst.

Description

technical field [0001] The invention relates to the field of vehicle test devices, in particular to an automobile tire burst simulation test device. Background technique [0002] Tire blowout, fatigue driving, and speeding are listed as the three major killers of road traffic, but because of the unpredictable and difficult control of tire blowout, it is also called "number one killer" and "invisible killer". In recent years, due to the increase of car ownership and highways in my country, traffic accidents caused by tire blowouts have remained high. According to authoritative statistics: At present, 46% of traffic accidents on highways in my country are caused by tire failures. A tire blowout accounted for more than 70% of the total number of tire accidents. Therefore, the tire blowout phenomenon of high-speed vehicles and its impact on vehicle handling stability and countermeasures are issues that relevant scholars and enterprises have to face. [0003] The current tire bl...

AI Technical Summary

Problems solved by technology

[0003]The current tire blowout simulation experiment is mainly realized by the following three methods. Restrictions, transportation and use are extremely inconvenient, and the cost is very high; the second is to use the solenoid valve to control the quick deflation device to realize the rapid deflation of the tire, but the deflation device needs to be specially made and is only suitable for a specific wheel hub; It is a device that punctures tires on the road where the vehicle is traveling. This type of tire blowout device is easy to be remembered by the driver, thereby reducing the suddenness and randomness of tire blowouts.

The driver may instinctively relax the accelerator when approaching the predetermined tire blowout area due to fear, so that the vehicle speed cannot be reached in advance, which weakens the effect of the tire blowout drill and widens the gap with the actual high-speed tire blowout situation
