双螺杆压缩机转子圆弧及圆弧包络线型线的几何构造

Geometry of Arcs and Their Evolution Profile of Twin Screw Compressors

从双螺杆压缩机圆弧及圆弧包络线的基本构造出发,根据各线段在连接点处应当是连续和导数连续的条件,导出了型线的参数应满足的方程。根据这些方程编写了MATLAB程序,并得出了阴阳转子型线的一种参数形式。

Based on equations of arcs and their evolution of twin compressor and conditions which their connections should be continuous and smooth, the equations that the profile should be satisfied had been derived. The equations had been programmed in Matlab, and profiles of male and female rotor is given by parametric types.
