AI Technical Summary

Technical Problem

Existing road surface skid resistance testing instruments cannot accurately simulate the real contact between tires and road surface under high-speed vehicle operation conditions, and cannot measure energy dissipation and braking distance, resulting in errors between test results and actual performance, which affects road traffic safety.

Method used

A dynamic energy dissipation type road surface anti-skid performance tester is used to simulate the real anti-skid performance of tires and road surfaces under different vehicle speeds by combining accelerated rotation with energy dissipation test modes. The energy dissipation between vehicle tires and road surfaces per unit distance is measured to evaluate the real anti-skid performance of highway road surfaces.

Benefits of technology

It enables accurate measurement of road surface anti-skid performance under simulated high-speed vehicle operation, and can truly reflect the braking distance under emergency braking conditions, filling the gap in existing technology and providing safe and reliable data support.
