Mathematic modeling and characteristic analysis for the intelligent compactor

The intelligent compactor, which embodies both the virtues of vibratory and oscillatory compaction, is an interesting field in recent theoretical and applied investigations on construction machinery. According to the mechanical character and operational principle of intelligent compactor, a multi-mode integrated model for dynamic system was put forward. The coupling characteristic between the horizontal and vertical direction was pointed out. The fact that the vibratory drum may slide with subgrade in the horizontal direction was thought over and the dynamic responses were investigated. The simulation results showed that the vibration wave would become aberrance and super-harmonic components occur accordingly, which were confirmed by the local experiments. This will help the compactor choose the vibration mode appropriately and make the intelligent compaction become feasible and effective, which provided a good foundation for the research and development of intelligent compaction technology.
