| Abstract: | The simply-supported beam and cantilever beam are the major research objects and the method of strain measurement is adopted to get the dynamic parameters of the beam under dynamic load, such as dynamic load factor, natural frequency, and damping factor. The process of parameters measurement with strain measurement technique and the method of data processing are introduced detailedly. The accuracy of the dynamic parameters measured is discussed. The strongpoints and shortcomings are analyzed. |
