Hysteresis Modeling and Analysis for Dynamic Compaction

Abstract:

The soil compactor is one of the most important construction machineries which play an significant role during our economic development. And the complicated nonlinear characteristic of equipment-material system is an interesting field in recent theoretical and applied investigations. According to experimental datum, a nonlinear model derived from piecewise linear was used to describe the hysteretic behavior of soil material during compaction. Through choosing proper model parameters, the nonlinear dynamic characteristics are commendably controlled which could represent different compacting stages. Furthermore, the series phase diagram and Poincare section were obtained by simulation. The hysteretic characteristics might be incarnating from periodic vibration to chaotic vibration. Further research proved that reducing the angular frequency of rotation may bring the chaotic vibration coming back to periodic vibration, which provided a good assistance for further study on hysteretic character of soil compaction and man-machine engineering on vibratory compacting system.
