| Abstract: | Aiming at the complex calculation problems of Monte Carlo method and improved first order second moment(IFOSM) method,performance scatter analysis of solid rocket motors based on tensor-product function was put forward.Analysis accuracy and efficiency of Monte Carlo method were compared with that of tensor-product function method through the examples.The results show that tensor-product function method can not only ensure high analysis accuracy,but also greatly improve analysis efficiency. |
