Abstract
The present invention relates to a tread rubber abrasion test device and test method thereof, and belongs to the test machinery technology field. The device overall comprises a closed box body, an air intake channel, a volatile organic compound (VOC) gas collection device, a suspended particulate matter collection device and an abrasion device. According to the present invention, the test rotating speed is controlled by a frequency converter, the test temperature is controlled by an air heater, the test load is controlled by adding a counterweight on a crossbeam, the suspended particulate matters are collected by a multi-stage collision particle sampler, a VOC gas is collected via an alkali liquor, and the abrasive dust is convenient to collect and a multiple abrasion test condition is realized by abrading a rubber wheel on the inner surface of a roller and by the tight connection of the roller and the front and back baffles. The present invention provides the device and the test method which can research the VOC discharge, the abrasive dust granularity distribution and the abrasive dust multiple abrasion during the tread rubber abrasion process.
Description
technical field [0001] The invention relates to a tread rubber abrasion testing device and a testing method thereof, belonging to the technical field of testing machinery. Background technique [0002] As the only important part of a car that is in contact with the ground, tires inevitably have friction with the road surface and wear during the rolling process. Therefore, it is of great significance to study the wear performance of tire tread rubber. [0003] At present, the most common equipment used to study the wear performance of rubber is the Akron Abrasive Machine, but the test conditions of the Akron Abrasive Machine are single, and the speed, load, and test temperature are not adjustable; at the same time, the test conditions are different from the actual working conditions of automobile tires. far. Therefore, it is difficult to reflect the wear resistance of the tread rubber by the wear amount obtained by the Akron abrasion machine with single and mild test conditi...
