| Abstract: | The horizontally-oscillatory and vertically-vibratory rollers are two typical categories of compacting machines for large basic constructions.By summarizing typical dynamical models of the horizontally-oscillatory and vertically-vibratory rollers,the advantages and disadvantages are first analyzed.Based on the working properties and dynamical model features regarding an intelligent roller with adjustable vibration mode,a nonlinear hysteretic dynamic model with slowly-varying parameters is then tackled in terms of time and space considerations during compacting process.Finally,the future directions to the proposed model are addressed. |

| Keywords: | horizontal oscillation vertical vibration hysteretic model slipping state jumping state |
