Abstract：

In this paper,a new quadrilateral mesh generation approach in sheet form simulation is presented,which based on quatree method.It not only preserves the advantages of good middle element and excellent adaptability of quatree method,but also overcomes the weakness of poor boundary element.It can generate arbitrary polygon regions with all quadrialateral,good quality element in high speed and has been used in the blank mesh of sheet forming simulation.The basic steps and the performance of the method are described in this paper.
