摘要
Abstract
According to the modal testing results of vibrating beams under different boundary conditions, the modal shape and material loss factor are obtained. Through the harmonic response computation, the peak values of the responses at the excitation point and the end of the beam and the loss factor of the material are derived. Comparing these results mutually, it can be concluded that the horizontally placed beam with one end excited and the other end free is the most reasonable. Finally, due to the shortage of the resonance data in the frequency range of the test, several sets of beam specimens with different lengths are tested.关键词
