Analysis of air flow of the semi-rigid solar array in ground vibration test

The air flow induced by vibration of the semi-rigid solar array was analyzed by using Boundary integral equation with dipole configuration method, in which added mass of air flow and vibration of the semi-rigid solar array coupling was described by dipole intensities. The error expression for added mass was described by the density of dipole. Based on the error analysis, a new extrapolative arithmetic for added mass was gained. Through the arithmetic, higher precision result can be obtained with lower dipole configuration density, which can improve computational efficiency and overcome the shortage of computing resource.
