摘 要本課題首先對國內(nèi)外高空作業(yè)車的發(fā)展進行了概括，提出了發(fā)展中的不足，簡要介紹了高空作業(yè)車的組成，然后對目前國內(nèi)生產(chǎn)技術(shù)不完善的混合臂和伸縮臂式高空作業(yè)車的關(guān)鍵結(jié)構(gòu)進行了設(shè)計，同時對工作斗調(diào)平技術(shù)和液壓系統(tǒng)等關(guān)鍵技術(shù)進行了研究分析。重點研究了伸縮臂的結(jié)構(gòu)、運動特點，并對其進行了強度校核。根據(jù)高空作業(yè)車安全性要求高，工作幅度大，結(jié)構(gòu)復(fù)雜等特點，提出了工作臂、副車架以及工作斗調(diào)平機構(gòu)的研究設(shè)計方法。該課題以混合臂式高空作業(yè)車為研究對象，詳細闡述了伸縮臂的結(jié)構(gòu)設(shè)計、變形研究；副車架結(jié)構(gòu)設(shè)計、工作穩(wěn)定性分析；高空作業(yè)車的工作斗調(diào)平系統(tǒng)的研究分析；液壓系統(tǒng)的設(shè)計計算。課題采用積分法對伸縮臂結(jié)構(gòu)進行應(yīng)力分析、變形分析。最后，對研究分析結(jié)果進行了試驗和驗證，將試驗結(jié)果和理論分析結(jié)果進行了對比，通過對比分析進一步驗證了本文提出的設(shè)計方法，對于同類型高空作業(yè)車研究計算，具有一定的參考價值。關(guān)鍵詞 ：高空作業(yè)車；結(jié)構(gòu)設(shè)計；調(diào)平系統(tǒng)研究；液壓缸AbstractThis paper arranged as follows. The first part is the summary of the development of aerial working platform at home and abroad, and put forward some shortages during the development. There is a brief introduction of the component parts of the aerial working platform. This paper introduces a new design proposal of the domestic production technology of mixing arm and telescopic arm aerial working platform. Meanwhile, the analysis can also be seen in the working bucket leveling, hydraulic systems and other key technology. This paper mainly focuses on the telescopic structure, movement characteristics, and its strength check. According to the special requirements of aerial vehicles because of the high security, large in range and the complicated structure, the special design was used in the working arm, subframe and bucket leveling institutions. The subject is based on the study of mixing arm of aerial working platform. The subject describes the structural design of the telescopic boom in detail, and analysis the design of subframe structure design and the job stability. The aerial working platform bucket leveling system analysis and hydraulic syetem design are also mentioned here.the subject adopts integration method on the telescopic structure stress analysis and deformation analysis. The results of research and analysis are also compared in this part. The new design method is created through comparative analysis. And it is an useful guideline for the same type of aerial working platform.Key words: Aerial working platform; Structure design; The research of leveling system; The hydraulic cylinder車載式高空作業(yè)平臺的結(jié)構(gòu)設(shè)計目 錄摘 要 .IIIABSTRACT IV目 錄 V1 緒論 .11.1 本課題的研究內(nèi)容和意義 11.1.1 課題研究背景 .11.1.2 課題研究的意義 11.2 高空作業(yè)機械的國內(nèi)外發(fā)展概況 .11.2.1 高空作業(yè)機械的國外發(fā)展狀況 .11.2.2 高空作業(yè)機械的國內(nèi)發(fā)展狀況 .21.3 高空作業(yè)車的組成 .21.3.1 專用底盤 .21.3.2 工作臂架 .31.3.3 三維全旋機構(gòu) .31.3.4 電氣與液壓系統(tǒng) .31.3.5 安全裝置 .31. 4 課題研究的內(nèi)容 42 伸縮臂結(jié)構(gòu)分析 52.1 伸縮臂的結(jié)構(gòu) .52.2 工況分析 .62.3 伸縮臂強度計算分析 .62.3.1 危險工況 1 計算 .72.3.2 危險工況 2 計算 .72.4 伸縮臂變形計算 .82.4.1 力學(xué)模型的建立 82.4.2 彈性位移的計算 92.4.3 計算結(jié)果 122.5 伸縮臂強度校核 .122.5.1 計算基本臂臂的截面尺寸 142.5.2 對下臂進行正應(yīng)力校核 .152.6 本章小結(jié) .163 副車架結(jié)構(gòu)及分析 173.1 副車架結(jié)構(gòu) .173.2 支腿反力的計算 .173.3 轉(zhuǎn)臺回轉(zhuǎn)系統(tǒng) .213.4 本章小結(jié) .224 工作斗調(diào)平機構(gòu)的研究 234.1 工作斗調(diào)平結(jié)構(gòu)模型 .234.2 調(diào)平機構(gòu)液壓系統(tǒng) 254.3 本章小結(jié) .265 液壓油缸的設(shè)計計算 275.1 伸縮變幅油缸的結(jié)構(gòu) .275.2 伸縮變幅油缸的設(shè)計計算 .275.2.1 確定液壓缸類型和安裝方式 275.2.2 確定液壓缸的主要性能參數(shù)和主要尺寸 275.3 本章小結(jié) .316 結(jié)論與展望 326.1 結(jié)論 .326.2 展望 .32致 謝 33參考文獻 .33附 錄 33
