Based On Chaotic Vibration Of A Polygon Work Roller Compaction Process Of Research

At present, the construction of the use of compaction equipments for morevibratory roller and impact roller, as compaction technology development andprogress, the engineering practice of medium voltage by former single static,vibration compaction development up to now the static, vibration, and so on themany kinds of impact compaction way composite construction, so as tostrengthen the purpose of compaction. Practice proves that the mostcomprehensive many kinds of compaction way of composite compactionadvantages, its comprehensive efficiency than single compaction method.Therefore, the study and explore new composite compaction way, for thedevelopment of the compaction technology has the important theoretical andpractical significance.Chaotic vibration compaction is compaction in the field of a new direction,in recent years in vibration compaction is used. Meet some of the conditions ofthe nonlinear vibration system, motivated by rules, also can produce seeminglyno rules never repeated response-chaotic vibration. It is rich in frequencycomponents and broad amplitude domain, can arouse be compaction materialswith different natural frequency of the various complex material form ofall-round resonance frequency domain. Luoyang construction machinery CoLTD LSD218GH developed vibratory roller work rounds, will be three sectionsof octagon wheel crisscross, with heavy plate ram with tremendous impactself-traveling single drum vibratory roller of high pressure double characteristicsof efficiency. The purpose of this paper is to will have broadband powerspectrum of the vibrator which chaos as incentive equipment, installation workin polygon wheel, the dynamic characteristics and compaction effect forresearch.In this paper, we design the installation CVE-2type chaos vibrator whichwork round the polygon system; Second set up chaos impact roller"rack-compaction wheels-soil" system, and the mathematical model ofmathematical model of the numerical simulation and chaos identification, based on the results of numerical simulation, the work of round of compaction processthe dynamic response characteristics of; Finally, the "chaos" and "ordinary"roller compaction result are analyzed and compared, and the results showed thatthe chaos of the installation vibrator which polygon roller compactionperformance than the installation monophonic vibrator which polygon roller.
