Tire Traction Slip Friction Tester TTT
The Tire Traction Slip Friction Tester (TTT) by Dynatest is a reliable device used to measure the peak friction characteristics on paved surfaces. It is specifically designed for tire testing to evaluate the dry or self-wetted friction characteristics of tires.
The TTT comprises a fully instrumented tow vehicle and test trailer, utilising a Dynatest two-axis force transducer to provide accurate measurements of vertical load and horizontal tractive force. As a pavement measurement device, it adheres to the requirements of ISO 23671 and 15222 for wet grip measurements of C1 and C2 tires, as well as standard ASTM-E274 and ASTM-F408.
- State-of-the-art electronic instrumentation ensures precise measurements, while the user-friendly, menu-driven Windows® software allows operators to easily enter and document multiple test parameters. The onboard laptop computer calculates the Skid Number (SN) and Peak Braking Coefficient (PBC) in real-time using the two-axis force transducer data. Test data is stored for future analysis.
- Additional software capabilities include automatic system calibration, comprehensive system diagnostics, and adjustable test cycle timing.
- The system is equipped with digital encoders to accurately measure distance and monitor test speeds. It includes a hand remote switch for initiating automatic tests, an industrial-rated PC, and a graphic printer.
- Test results can be displayed graphically and numerically, providing a comprehensive overview for operators. The computer automatically controls all phases of the testing cycle.
- The system software features a Calibration function, allowing operators to calibrate the two-axis force transducer. The computer calculates gain and offset values for the force transducer and displays the results graphically.
- Optional features include DGPS for precise positioning, an integrated Selcom texture laser, a dual-side water system, blocking bars, stainless steel C1 trailers for enhanced durability, and a variety of tow vehicles and water tank sizes.
The Tire Traction Slip Friction Tester (TTT) offers advanced capabilities for assessing tire friction characteristics, providing accurate measurements and comprehensive software functionalities for efficient testing and analysis.
