【摘要】：随着汽车工业的迅猛发展,汽车空调系统也越来越受到了重视。制冷压缩机作为汽车空调的核心同时得到了飞速的发展。旋叶式压缩机具有结构简单、体积小、维修方便、动力平衡性好等优点在压缩机市场具有极大的潜力。本文在以往的对旋叶式压缩机研究的基础上,对旋叶式压缩机做了进一步的研究。主要有以下几方面: 1、具有普遍适用性的旋叶式压缩机叶片头部型线; 通过对叶片头部型线深入的研究,创造性的提出一种具有普遍应用性的叶片头部型线,适用于任何的旋叶式压缩机气缸型线。具有均匀磨损、易于制造以及良好的润滑、密封性等优点。 2、建立旋叶式压缩机的压缩气体状态模型同时对排气量模型进行深入研究; 通过对旋叶式压缩机工作过程中基元的变化,及气体的性质对压缩气体的压力做了深入的探讨,同时对油气两相泄漏做了深入的研究,在此基础上建立了排气量模型。 3、建立旋叶式压缩机的运动学、动力学模型以及功率效率模型; 通过以叶片圆心的轨迹作为气缸型线的替代,省略了对叶片头部型线与气缸内壁接触点的复杂求解过程,根据运动学、动力学原理,对旋叶式压缩机叶片建立运动学动力学模型,大大简化了其复杂程度并且具有足够的准确度。同时对旋叶式压缩机的功率以及效率问题做了进一步的分析。 4、开发计算机辅助设计系统。通过以上的数学模型,通过对其进行数值计算以及数据整理,整理之后的数据通过使用C++Builder6.0对其仿真,实现旋叶式压缩机的设计实现快速可视化,真正的做到设计、分析、制造一体化,大大的加快旋叶式压缩机的设计分析速度。
[Abstract]:With the rapid development of automobile industry, more and more attention has been paid to automobile air conditioning system. As the core of automobile air conditioning, refrigeration compressor has been developed rapidly. The rotary vane compressor has great potential in compressor market with the advantages of simple structure, small volume, convenient maintenance and good power balance. Further research on the rotary vane compressor has been done. The main contents are as follows:. 1. The blade head profile of the rotary vane compressor with universal applicability; Through the deep research on the blade head profile, a kind of blade head line with universal application is creatively proposed, which is suitable for any rotary vane compressor cylinder line. It has uniform wear, easy manufacture and good lubrication. The advantage of sealing, etc. (2) the compressed gas state model of rotary vane compressor is established and the exhaust volume model is studied deeply. The pressure of compressed gas is deeply discussed through the change of unit in the working process of rotary vane compressor and the nature of gas. At the same time, the leakage of two phases of oil and gas is studied deeply, and the exhaust volume model is established. 3. The kinematics, dynamics model and power efficiency model of rotary vane compressor are established. By using the track of the center of the blade as the replacement of the cylinder profile, the complex solution process of the contact point between the blade head profile and the cylinder inner wall is omitted. According to the kinematics and dynamics principle, The kinematics and dynamics model of the blade of the rotary vane compressor is established, which greatly simplifies its complexity and has sufficient accuracy. At the same time, the power and efficiency of the rotary vane compressor are further analyzed. 4. Develop computer aided design system. Through the above mathematical model, through the numerical calculation and data collation, the data after finishing through the use of C Builder6.0 to its simulation, the design of the rotary vane compressor to achieve rapid visualization, truly achieve design, analysis, Manufacturing integration, greatly accelerate the speed of design and analysis of rotary vane compressor.
