【摘要】：针对传统的双螺杆压缩机转子型线的正向设计方法,计算过程繁琐复杂,且无法预判型线综合性能的问题,在深入研究啮合线与转子型线间关系的基础上,提出一种反向设计方法:通过设计啮合线反求获得阴阳转子型线。建立反向设计时阴阳转子的坐标转换关系,基于啮合原理推导反向设计阴阳转子型线的具体过程,分别以几种典型曲线作为啮合线段反求阴阳转子型线方程。在GHH型线的研究基础上,自行设计了一条啮合线,反向推导计算出一对阴阳转子型线进行流体分析并与GHH型线对比,发现该反向设计转子型线与GHH型线性能接近。结合实验结果表明,反向设计方法可有效应用于螺杆转子型线设计。
[Abstract]:In view of the traditional forward design method of rotor profile of twin-screw compressor, the calculation process is complicated, and the comprehensive performance of the profile line can not be forecasted. On the basis of deeply studying the relationship between meshing line and rotor profile line, In this paper, a reverse design method is put forward: the rotor profile of yin and yang is obtained by reverse design of meshing line, and the coordinate transformation relation of rotor of yin and yang in reverse design is established, and the concrete process of reverse design of profile of rotor of yin and yang is deduced based on the meshing principle. On the basis of the research of GHH profile, a meshing line is designed and a pair of yin-yang rotor profile lines are derived and analyzed by reverse derivation and compared with GHH type lines. It is found that the linear energy of the rotor profile of the reverse design is close to that of the GHH type. The experimental results show that the reverse design method can be effectively applied to the profile design of the screw rotor.
