This paper also analyzed the design process of lines, the geometry features of the rotor and the calculation method of thermodynamic property. Based on the analysis of the design process of lines, geometric characteristics and calculation methods of thermal performance, this paper selected the unilateral asymmetry cycloid - sales arc tooth profile of the screw compressor rotor type lines for analysis and calculation using MATLAB and other tools. After above steps, the equation-based and sketch-based line are given the calculation of geometry features and thermal performance are also made. On the basis of rotor design, this paper gave stress analysis and selected bearing and other parts using a variety of analysis software to. Afterwards, the paper established three-dimensional models of the various parts of the screw compressor and carried out the assembly to complete the three-dimensional modeling of the screw compressor. With the application of ADAMS, the paper established motion simulation of the assembly imported from SOLIDWORKS, which could explain the issue vividly and intuitively. Key words: Screw compressor, three-dimensional modeling, MATLAB, motion simulation 目 錄 第一章 緒論--------------------------------------------------------1 1.1基本結(jié)構(gòu)和工作過(guò)程-----------------------------------------------1 1.1.1基本結(jié)構(gòu)-----------------------------------------------------1 1.1.2工作過(guò)程-----------------------------------------------------1 1.2螺桿壓縮機(jī)特點(diǎn)及分類---------------------------------------------2 1.2.1螺桿壓縮機(jī)特點(diǎn)-----------------------------------------------2 1.2.2螺桿壓縮機(jī)分類-----------------------------------------------2 1.3螺桿壓縮機(jī)發(fā)展歷程-----------------------------------------------3 1.4論文主要工作-----------------------------------------------------4 第二章 轉(zhuǎn)子型線設(shè)計(jì)------------------------------------5 2.1轉(zhuǎn)子型線發(fā)展過(guò)程-------------------------------------------------5 2.2型線方程和嚙合線方程---------------------------------------------6 2.2.1坐標(biāo)系建立和坐標(biāo)變換-----------------------------------------6 2.2.2齒曲線及其共軛曲線-------------------------------------------8 2.2.3共軛曲線和嚙合線方程-----------------------------------------9 2.3單邊不對(duì)稱擺線-銷齒圓弧型線的設(shè)計(jì)--------------------------------10 第三章 幾何特性計(jì)算--------------------------------------------20 3.1轉(zhuǎn)子螺旋齒面及其法線方程----------------------------------------20 3.1.1螺旋齒面方程------------------------------------------------20 3.1.2轉(zhuǎn)子幾何參數(shù)間的基本關(guān)系------------------------------------21 3.1.3螺旋齒面的法線----------------------------------------------21 3.2接觸線----------------------------------------------------------23 3.2.1相對(duì)運(yùn)動(dòng)速度------------------------------------------------23 3.2.2嚙合條件----------------------------------------------------24 3.3齒間面積和面積利用系數(shù)------------------------------------------25 3.3.1齒間面積----------------------------------------------------25 3.3.2面積利用系數(shù)-----------------------------------------------27 3.4齒間容積和內(nèi)容積比---------------------------------------------27 3.4.1齒間容積---------------------------------------------------27 3.4.2內(nèi)容積比---------------------------------------------------28 第四章 熱力性能計(jì)算--------------------------------------------30 4.1內(nèi)壓力比和壓力分布圖-------------------------------------------30 4.1.1內(nèi)壓力比---------------------------------------------------30 4.1.2壓力分布圖-------------------------------------------------31 4.2容積流量及容積效率---------------------------------------------32 4.2.1理論容積流量-----------------------------------------------32 4.2.2容積效率---------------------------------------------------32 4.2.3實(shí)際容積流量-----------------------------------------------33 4.3軸功率---------------------------------------------------------33 第五章 轉(zhuǎn)子受力分析--------------------------------------------35 5.1軸向力---------------------------------------------------------35 5.1.1端面軸向力-------------------------------------------------35 5.1.2氣體軸向力-------------------------------------------------37 5.2軸承支反力-----------------------------------------------------40 第六章 三維造型和選擇軸承-------------------------------------44 6.1三維造型-------------------------------------------------------44 6.1.1轉(zhuǎn)子造型---------------------------------------------------44 6.1.2機(jī)體和端蓋造型---------------------------------------------48 6.2選擇軸承-------------------------------------------------------49 6.2.1選擇圓柱滾子軸承-------------------------------------------49 6.2.2選擇角接觸球軸承-------------------------------------------50 6.3軸承三維造型---------------------------------------------------54 6.4整機(jī)裝配-------------------------------------------------------55 第七章 運(yùn)動(dòng)仿真----------------------------------------57 7.1 模型導(dǎo)入Adams-------------------------------------------------57 7.2運(yùn)動(dòng)仿真-------------------------------------------------------57 結(jié)論------------------------------------------------------------------61 致謝------------------------------------------------------------------62 參考文獻(xiàn)-------------------------------------------------------------63 5
