摘要
水平振荡压路机和垂直振动压路机是大型工程基础施工中最典型的2种压实机械,概述了国内外几种典型振荡振动动力学模型,分析了其模型特点.模式可调的智能振动压路机,基于水平和垂直振动的工作特点,结合水平振荡和垂直振动动力学模型特点,且考虑被压实物料在压实过程中时间上参数慢变和空间上力与位移的非线性滞回特性,提出了1种基于慢变参数滞回非线性整体动力学模型,并对模型的进一步研究提出展望.
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.
