摘 要
本文通過對我國汽車舉升機現(xiàn)狀的調(diào)查、研究、分析,參考國內(nèi)外解決舉升機安全與穩(wěn)定性問題的解決措施,對幾種舉升機進行了分析,并結合我國舉升機存在的實際情況,提出了適合我國汽車修理行業(yè)的四柱式汽車舉升機設計方案。
本文首先闡述了四柱式汽車舉升機設計的目的和意義、發(fā)展狀況以及應用前景。分析論證了一種舉升承載質(zhì)量為3.5t的四柱式汽車舉升機總體設計方案,進行了舉升機構的機械系統(tǒng)、液壓系統(tǒng)、電氣系統(tǒng)等主要機構的方案分析和選擇,并對機械部分進行了運動分析以及強度和剛度的校核計算,對液壓系統(tǒng)及電氣系統(tǒng)進行了設計和計算。本課題基于計算機仿真平臺,應用當前CAD/CAE領域應用比較廣泛的二維軟件AutoCAD、三維軟Pro/E、有限元軟件ANSYS及動力學仿真軟件ADAMS,進行汽車舉升機二維圖紙設計、三維實體建模、舉升機的強度、剛度、穩(wěn)定性及動態(tài)特性等方面的計算機仿真研究與分析,可以代替舉升機物理樣機的前期試驗,為我國汽車舉升機產(chǎn)品的設計、技術開發(fā)方面提供更多的理論參考,進一步提高國產(chǎn)汽車舉升機的穩(wěn)定性和可靠性,提高產(chǎn)品的市場競爭力。

ABSTRACT
In this paper, the status quo of China's automotive lift investigation, research, analysis, refer to lift at home and abroad to resolve the issue of security and stability of the solutions of several lift analysis, combined with the existence of our country lift the actual situation, put forward for China's auto repair industry, four-post car lift design.
This paper described the first four-post car lift for the purpose and significance of design, development and application prospects. Analysis demonstrated that the quality of a 3.5t load lifting the four-post car lift design program, a lifting mechanism of the mechanical system, hydraulic system, electrical system and other major institutions of program analysis and selection, and mechanical parts of the motion analysis, as well as strength and stiffness of the calculation of the calibration of the hydraulic system and electrical system design and calculation. The subject of computer-based simulation platform, the application of current CAD / CAE broader field of application of two-dimensional software, AutoCAD, three-dimensional soft-Pro / E, the finite element software ANSYS and dynamic simulation software ADAMS, two-dimensional drawings for the design of car lift, three-dimensional Solid Modeling, lift the strength, stiffness, stability and dynamic characteristics of such areas as research and analysis of computer simulation, can replace the lift of the pre-physical prototype testing, car lift for our product design, technology development theory to provide more information to further improve China-made auto lift stability and reliability, and increase market competitiveness.
