摘要

摘要: 为了能够使智能化振动压路机在不同的压实阶段下进行最有效的压实作业,通过建立连耦工况下"振动轮-土体"四自由度动力学模型,分析得到了不同工作参数与振动轮及机架位移之间的关系,采用计算得到的模拟参数进行优化,得到了压实度最大且不引起跳振时的激振频率和激振角度,为振动压路机在各压实阶段下参数的优选提供数值依据。数据表明:随着土体状况的变化,压路机的激振频率保持在土体2阶固有频率的1.29~1.39倍范围内作业时,土体压实度达到最大值。

Abstract: For the purpose of making the most effective compacting operation of intelligent vibratory roller under different compaction stages, this paper analyzes the relationship between the vibrating wheel, rack displacement and different parameters, through establishing the four-degree of freedom dynamic model of vibrating wheel-soil body under the coupling operating condition. Besides, by optimizing the calculated parameters, the best vibration frequency and vibration angle are obtained so that the compacting is the biggest and also does not cause jumping vibra-tion, which provides the numerical basis for the parameter optimization of intelligent vibratory roller under different compaction stages. The result indicates that the degree of soil body compactness will reach maximum when the vi-bration frequency of vibratory roller keeps in the range of 1.29～1.39 times of soil body's second order frequency.
