Anonymous Function Method and its Application in Screw Pump’s Design and Processing
Matlab anonymous function method combining graph with analytical method was proposed in this paper, which was based on the low solving efficiency and low precision of trigonometry transcendental equation for shape line design and sectional profile calculation of screw pump rotor. Parameters of anonymous function can be nested within each other to solve enveloping conditional formula of shape design or intersecting line of sectional profile design for screw pump, the process of which only took several seconds with high precision of 10E-08mm. What’s more, this method could also be adopted in the forming tool design with spiral cross section, which could largely improve design efficiency and calculation precision.
