Abstract

The dynamics mathematical model of the driving wheel of vibro-roller-soil system is established, and the theoretical analysis and the simulation research of continuous detection for vibro-roller compactness are carried on. The relations of the vibrating wheel acceleration, the compact soil rigidity and damping are obtained; and then the method of measuring compactness indirectly through detecting vibrating wheel acceleration of the vibro-roller is proposed, and the continuous detection system of the vibro-roller compactness is developed based on above mentioned. The experiments indicate that the method and the developed system can realize the continuous detection of soil compactness, and can apply to engineering practice.
