Abstract: When the spacecraft structural dynamic model is updated using test data, the freedom of FEM can be matched with test freedom by means of reduction method. A new method of iterative matrix reduction based on Guyan reduction and IRS reduction is brought forward, which has low converge speed but with high analysis accuracy.
