The instrument is a fatigue load dynamic water erosion coupling testing machine, specifically engineered to simulate the combined effects of wheel rolling compaction and dynamic water erosion. It replicates real-world road surface conditions on rainy days where accumulated water interacts with heavy vehicle traffic.
The system is decomposed into six main modules: main frame, dynamic water test chamber, loading system, water pressure supply system, drive system, and control system.
Equipped with high-pressure nozzles and a circulation tank. Water pressure is adjustable from 0-1MPa with an accuracy of 0.05MPa, simulating high-speed tire splash effects.
Features rubber-tired wheels performing reciprocating motion at 1Hz. Loading pressure is adjustable within 10-25KN to simulate heavy vehicle compaction.
During operation, the dynamic water test chamber can accommodate 5 concrete small beam specimens (40cm × 10cm × 10cm) simultaneously. The driving system utilizes a crank and connecting rod mechanism to drive the wheels in a repeated rolling motion, accurately simulating four-point bending fatigue loading and three-point fatigue scenarios.
