| 摘 要： | 利用边界积分方程的偶极子配置法分析半刚性电池板地面振动诱导的空气流场,导出附加质量关于偶极子配置密度的误差表达式.由此建立了基于偶极子配置法的附加质量外推计算方法,只需采用较低密度的偶极子配置便可得到较高精度的附加质量计算结果,提高了计算效率,也克服了计算资源的不足.

| Abstract: | 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 dipol... |
