In contrast to phase separation ( curve - fitting ) approaches which are largely mathematical , phase resonance testing is a physical technique . when a structure is vibrating in a normal mode , the undamped natural frequency and normal - mode shap of the structure are directly measured . in the classic phase resonance testing , the test data processing is simpler and the results are more accuracy 相對于相位分離法來說,相位共振法是一種比較直觀的物理識別方法,在結構做“純模態”振動時,通過物理測量直接獲得模態參數;試驗數據處理工作量小,且精度一般比單輸入系統高。

Finally , floquet ' s theory is used to generate - dynamic stability system equations for the purpose of determining both undamped and damped instability regions 最后采用floquet理論求得考慮阻尼及不考慮阻尼時確定動力失穩區間的控制方程。
