  1. 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。
