摘　　要：采用反向设计方法(啮合线法)对双螺杆压缩机转子型线设计研究。推导出能表征双螺杆压缩机综合性能的表达式,为灵活设计,将NURBS引入螺杆转子啮合线的设计研究中,在已知基本参数条件下,对啮合线的基点进行确定。根据基点啮合线进行分段。基于NURBS控制点具有局部控制的机制,以综合性能指标为寻优函数,对分段的啮合线进行寻优反向设计转子型线。The rotor profile design of twin-screw compressor is studied by reverse design method,also called meshing line method.In order to be flexible,NURBS was introduced into the design and research of the meshing line of screw rotor.Under the condition of known basic parameters,the basis points of the meshing line were determined.Section according to the meshing line of base point.Based on the local control mechanism of NURBS control points,the rotor profile was reverse designed by optimizing the meshing line of segments with the comprehensive performance index as the optimization function.
