- Abstract:
- Based on the establishment of the dynamic model of oscillating compaction, a large number of field tests were carried out on the amplitude-frequency characteristics of the roller during the oscillation compaction process, and a dynamic identification method for the stiffness and damping of the compacted material in the dynamic model was proposed. The actual test curve is simulated by computer simulation test of the dynamic model, and the fitting curve is obtained by the trial method for different stiffness and damping, so that the stiffness and damping values can be determined. The results show that the change trend of the actual amplitude-frequency characteristics highlights the characteristics of the two degree-of-freedom systems in the theoretical model of the interaction between the oscillating wheel and the hot asphalt mixture, and the stiffness and damping determined by the dynamic identification method are similar to the actual change trend of the compacted material during the compaction process.
