AI Technical Summary

Problems solved by technology

[0003] The trailer-type outdoor tire testing machine can simulate the operation of tires in various road conditions, but due to the randomness of the outdoor environment and the influence of factors such as uneven road surfaces, the obtained test data is not accurate and has a large dispersion

The indoor tire testing machine eliminates the influence of the outdoor environment on the tire test data. In addition to simulating the relative movement between the road surface and the wheels, this kind of testing machine can usually realize tire side deflection and roll motion, but due to imperfect mechanism principles, it is common. The problem of the movement of the center of the tire footprint during the rolling and yaw motion causes the marginal effect of the roll motion coupling that cannot be eliminated, such as the widely used flat-belt high-speed tire mechanical characteristic testing machine produced by the American MTS company. , which makes it difficult to control the motion input parameters of the test tire, resulting in inaccurate test data

In addition, the current testing machine that can test the characteristics of tire composite working conditions has a complex structure, large size, and high cost
