Abstract

The invention discloses a tire test device. The tire test device includes: a rotatable drum, wherein the inner circumferential surface of the rotatable drum is provided with a replaceable simulation road surface, and a tire can be rotatably arranged on the simulation road surface; and a tire adjustment mechanism which is connected to the tire and is used for adjusting the position and / or the angle of the tire relative to the simulation road surface. The tire test device can achieve rolling performance test and analysis of the tire at different rolling speeds, side slip angles and side inclination angles, under different loads, and in different road surface situations, can acquire a test result having high correlation with an outdoor test, and can provide strong help for rolling performance research of the tire.

Description

technical field [0001] The invention relates to a tire testing device. Background technique [0002] The mechanical properties of tires have an important influence and significance on the design and production of tires, the matching of tires and automobile chassis, and the performance of the whole vehicle. Using experimental methods to analyze and obtain the mechanical properties of tires is an important supplement to the study of tire performance by mathematical analysis methods. and means of obtaining relevant data. Generally, there are two ways to test tire mechanical properties: indoor test bench tire test and outdoor test. Carrying out tire performance tests on indoor testing machines can overcome unfavorable factors such as temperature, weather, driver skills, and non-repeatability of tests, and can design test plans for specific test objectives. [0003] Compared with so-called "flat belt" and external drum testing machines, internal drum tire testing machines can a...
