Based on the study of the exchange of displacement date between fluid and structural meshes in fluid-structure interaction simulation, a method of the improved Constant Volume Transformation (CVT) has been proposed and illustrated in this paper. The quality of interpolated meshes are ensured by introducing an area factor. Interpolating calculations are performed for two conventional configurations: three dimensional wing and missile body. And compared with Infinite Plate Spline (IPS) method and evaluated errors, it is believed that the improved CVT method can avoid abnormal case of primary CVT metod being likely to happen, and the method is more accuracy and efficiency compared with IPS method.
