| Abstract: | Using the formation principle of engineering curved surface,vane blade and front tray,the core construction of contrifugal type windmill vane,are researched in construction analysis and mathematical medole building. It is proved that the intersecting line of the two curved surface is space curve,and the equation is quartic implicit function with one unknown. Using the Nouton's iterative method,the mathematical equation and program block diagram to solve the intersecting line of the two curved surface is built. |
