　　In the structural dynamics optimization of spacecraft,global modes and the associated natural frequencies are significant to design.However,when global natural frequencies are constrained in optimization model,the orders of them are likely to drift.This phenomenon is called mode switching (i.e.,frequency crossing) and it will lead to an unreliable design.An alternative approach to overcome the difficulties is mode identification method.
