Research on Surface Modeling of Turbo Vane of Vehicle Based on NURBS

Abstract

Abstract In order to verify the induced inverse matrix equation for the control vertices of quartic NURBS curve and to improve the construction accuracy and fairness of complex twisted surface, this work constructed the bi-quartic NURBS surface of turbo vane of vehicle with NURBS technology in MATLAB. The bi-quartic NURBS vane of turbo was reconstructed in CATIA. The results were compared with the bi-cubic NURBS surface of vane in the same data, and the bi-cubic NURBS surface were constructed with the current inverse matrix equation for the control vertices of cubic NURBS curve. It shows that the constructed surface of vane with the generalized method of modeling of quartic NURBS surface has better accuracy and fairness through analyzing the error and fairness. The work provides the reference for the accurate modeling and the high-accuracy, high-efficiency NC machining of turbo vane in the engineering application.
