| Abstract: | This paper advances a nonlinear dynamic model dealing with the jump vibration for the drum of a vibratory roller. The simulations show that subharmonics may occur while the drum is taking a jump vibration,which is likely to turn into chaos under some conditions.The field measurement supports the theoretical results.The conclusions in this paper may be useful for the condition monitoring of a vibratory roller and the estimation of the soil compaction. |
