Dynamic Rollers in Earthworks: Compaction and Continuous Compaction Control
The quality of earth structures highly depends on the compaction state of fill layers, which can be made up of a wide range of various materials. Compaction is usually accomplished by vibratory rollers; the vibration of the drum is generated by rotating eccentric masses. Moreover, dynamic rollers with different types of excitation have been developed in the last decades, including rollers with ...
متن کاملNumerical simulation of dynamic soil compaction with vibratory compaction equipment
Roller drums make use of various shapes and their dynamic compaction effect is achieved by different kinds of dynamic excitation systems. The bearing capacity of layered soil constructions can be measured during the soil compaction process. The finite element method has been applied for dynamic analyses using elastic models. For the realistic simulation of the dynamic compaction process it is n...
متن کاملA Reverse Driving Control Method for Hydrostatic Double-drum Vibratory Rollers
A reverse driving control method for hydrostatic double-drum vibratory rollers is devised in this paper. Based on the analysis of dynamic characteristics of stopping process, the relationship equation between engine speed and pump displacement is established. To restrict the peak value of engine overspeed within the allowable region, an offline parameter determination approach complied with the...
متن کاملGlassy dynamics in granular compaction: sand on random graphs.
We discuss the use of a ferromagnetic spin model on a random graph to model granular compaction. A multispin interaction is used to capture the competition between local and global satisfaction of constraints characteristic for geometric frustration. We define an athermal dynamics designed to model repeated taps of a given strength. Amplitude cycling and the effect of permanently constraining a...
متن کاملMechanics for vibratory manipulation
Vibratory manipulation is any mode of manipulation involving repeated impacts due to a striker which follows some periodic motion. In this paper, we study vibratory manipulation in the context of tapping planar objects which slide on a fixed support surface. We are interested in the behaviors an object exhibits under such excitation. There are two distinct types of tapping that can result: cont...
