【摘要】：路緣石滑模攤鋪機是一種通過特定模具鋪出多種形狀路緣石的工程機械,廣泛應(yīng)用于道路兩邊的路緣石、攔水帶以及農(nóng)業(yè)灌溉排水渠的施工�，F(xiàn)階段,我國對這種機械研究領(lǐng)域多為自走式滑模攤鋪機的研究,對于牽引式滑模攤鋪機的研究非常少,因此本文有必要對牽引式滑模攤鋪機進行系統(tǒng)設(shè)計和研究分析。通過本文的研究,在國內(nèi)外先進攤鋪機械研究的基礎(chǔ)上,形成關(guān)于牽引式滑模攤鋪機系統(tǒng)性設(shè)計理論,對今后牽引式滑模攤鋪機工程實際應(yīng)用具有現(xiàn)實理論指導(dǎo)意義。本文主要內(nèi)容包括:第一章總體介紹了課題的研究背景和意義,并詳細闡述了國內(nèi)外路緣石滑模攤鋪機的發(fā)展趨勢和應(yīng)用領(lǐng)域。其中論文闡述了我國路緣石滑模攤鋪機當(dāng)前的研究現(xiàn)狀和我國研究跟國外先進技術(shù)的差距何在。重點介紹了螺旋式和擠壓式滑模攤鋪機的各自優(yōu)缺點,并重點講述當(dāng)前背景下研發(fā)牽引式路緣石滑模攤鋪機重要意義,并闡述牽引式路緣石滑模攤鋪機的市場前景和應(yīng)用前景。第二章以秦皇島盧龍華通工程機械廠生產(chǎn)的HT750滑模攤鋪機為借鑒對象,并以牽引式路緣石滑模攤鋪機為研究對象,介紹了該機的組成、應(yīng)用范圍及工作原理,分析計算了生產(chǎn)率、發(fā)動機功率等主要技術(shù)參數(shù),同時對路緣石滑模攤鋪機進行各個零部件的三維實體設(shè)計,并進行整體裝配。第三章利用ANSYS軟件,對牽引式路緣石滑模攤鋪機的車輪軸、連桿等關(guān)鍵受力部件進行三維幾何模型建立和線性靜力結(jié)構(gòu)分析。通過分析,列出了車輪軸、連桿的受力變形圖、Mises等效應(yīng)力云圖,分析出了車輪軸易變形區(qū)域,找到了容易發(fā)生應(yīng)力集中的區(qū)域,進而改善軸的材料、尺寸等參數(shù)。第四章利用ANSYS軟件中的模態(tài)分析模塊對滑模機的車輪軸進行有限元模態(tài)分析。論文了解車輪軸的共振區(qū)域,為結(jié)構(gòu)設(shè)計提供一定的指導(dǎo),得到對應(yīng)前十五階固有頻率,得到對應(yīng)的變形分布圖。第五章根據(jù)牽引式滑模攤鋪機的工況要求進行各個系統(tǒng)零部件的設(shè)計與選型,為液壓調(diào)平系統(tǒng)的設(shè)計奠定了基礎(chǔ)。同時,對攤鋪機進行了裝機試驗以驗證整機運行是否可靠。
[Abstract]:The road edge stone slide form paver is a kind of construction machinery which can spread various shapes of road edge stone by special mould. It is widely used in the construction of road edge stone, water retaining belt and agricultural irrigation drainage canal on both sides of the road. At present, the research of this kind of mechanical research field is mostly self-moving sliding form paver, but the research of traction sliding form paver is very few, so it is necessary for this paper to carry on the systematic design and research analysis to the traction sliding form paver. Based on the research of advanced paving machinery at home and abroad, the systematic design theory of traction sliding form paver is formed, which is of practical theoretical significance to the practical application of traction sliding form paver in the future. The main contents of this paper are as follows: in the first chapter, the research background and significance of the subject are introduced, and the development trend and application field of the road edge stone sliding form paver at home and abroad are described in detail. Among them, the paper expounds the current research status and the gap between our country's research and foreign advanced technology. This paper mainly introduces the advantages and disadvantages of spiral and extruded sliding form pavers, and emphasizes on the significance of developing traction slide form pavers on road edge under the current background, and expounds the market prospect and application prospect of traction slide form pavers. The second chapter takes the HT750 sliding form paver produced by Lulong Huatong Engineering Machinery Factory of Qinhuangdao as the reference object, and takes the traction type road edge stone slide form paver as the research object, introduces the composition, application scope and working principle of the machine. The main technical parameters, such as productivity and engine power, are analyzed and calculated. At the same time, the 3D solid design of each component is carried out and the whole assembly is carried out. In chapter 3, the three dimensional geometric model and the linear static structure analysis of the wheel shaft, connecting rod and other key force components of the traction road edge stone sliding form paver are established by using ANSYS software. Through analysis, the stress deformation diagram of wheel shaft and connecting rod, Mises equivalent stress cloud diagram are listed, the easy deformation region of wheel shaft is analyzed, and the region where stress concentration easily occurs is found, and then the material and dimension of axle are improved. In chapter 4, the modal analysis module of ANSYS software is used to analyze the wheel shaft of sliding mode machine by finite element method. In this paper, the resonance region of the wheel shaft is understood, which provides some guidance for the structural design, and obtains the first 15 natural frequencies and the corresponding deformation distribution map. In the fifth chapter, according to the working conditions of the traction sliding form paver, the design and selection of the parts and components of the system are carried out, which lays a foundation for the design of the hydraulic leveling system. At the same time, the paver is tested to verify the reliability of the machine.
