【摘要】：熨平板是攤鋪機(jī)施工過(guò)程中路面成型的主要部件,它的剛度尤其是垂向剛度對(duì)路面的平整度有重要影響。本文所研究的超大寬度熨平板,最大攤鋪寬度為16.5m,如何保證熨平板具有良好的靜動(dòng)態(tài)特性是一個(gè)行業(yè)前沿課題。 為開(kāi)發(fā)出滿(mǎn)足施工要求的超大寬度熨平板,首先對(duì)成熟的9m寬度熨平板做了剛度仿真和實(shí)驗(yàn)標(biāo)定,設(shè)計(jì)可靠的研究方法。 然后對(duì)16.5m寬超大熨平板幾何建模,建立有限元模型并做剛度計(jì)算,包括靜剛度、模態(tài)和攤鋪工況仿真。仿真結(jié)果顯示,當(dāng)熨平板寬度達(dá)到16.5m后剛度大幅下降,即使安裝垂向支撐機(jī)構(gòu)依然不能保證足夠的剛度； 為了得到剛度最優(yōu)的熨平板,拓?fù)鋬?yōu)化垂向支撐機(jī)構(gòu),并對(duì)優(yōu)化結(jié)果進(jìn)行可制造化設(shè)計(jì),仿真驗(yàn)證設(shè)計(jì)方案的靜動(dòng)態(tài)特性； 最后,研究熨平板在振動(dòng)器作用下的穩(wěn)態(tài)響應(yīng),探討合適的激振頻率范圍,比較安裝垂向支撐機(jī)構(gòu)前后熨平板動(dòng)態(tài)響應(yīng)特性,進(jìn)一步評(píng)價(jià)了垂向支撐機(jī)構(gòu)對(duì)熨平板剛度的影響。
[Abstract]:Ironing plate is the main component of pavement shaping in the construction process of paver. Its stiffness, especially vertical stiffness, has an important effect on the smoothness of pavement. The oversized ironing plate studied in this paper has a maximum spreading width of 16.5m.How to ensure that the ironing plate has good static and dynamic characteristics is a frontier issue in the industry. In order to develop a super wide ironing plate which can meet the requirements of construction, the stiffness simulation and experimental calibration of the mature 9m wide ironing plate are done first, and a reliable research method is designed. The finite element model is established and the stiffness is calculated, including static stiffness, modal and paving condition simulation. The simulation results show that when the width of ironing plate reaches 16.5m, the stiffness can not be guaranteed enough even if the vertical bracing mechanism is installed, and in order to obtain the optimum ironing plate stiffness, the topology optimizes the vertical support mechanism. The static and dynamic characteristics of the design scheme are verified by simulation. Finally, the steady state response of the ironing plate under the action of the vibrator is studied, and the suitable exciting frequency range is discussed. The dynamic response characteristics of ironing plate before and after installing vertical brace are compared and the influence of vertical bracing mechanism on plate stiffness is further evaluated.
