Abstract:

According to the characteristics of machinery and the principle of operation,an integrated coupling model for intelligent roller with adjustable vibration mode was put forward.During compaction, the fact that the vibratory drum may contact,slide or lose of
contact with subgrade was thought over and the corresponding mathematic model was
presented. Taking the YZC12 intelligent roller as an example, the dynamics response characteristics were investigated with different vibration modes comparing with the results of oscillation model with single vibration mode.Furthermore,experiments on asphalt
compaction were carried out to determine the validity of the present model.The results show that the single-mode model is unsuitable for this new kind of intelligent roller.It is rational to consider the coupling characteristics of vibration system between the vertical direction and the horizontal direction.

Key words: intelligent compaction;vibration mode;dynamics model;coupling characteristics
