| Abstract: | The relationship between the transverse natural frequency and the axial load of simply supported beam is studied. The conclusion is that the relationship between ~2_1-P is a straight line, while _1-P is a parabola. The influence of axial load on vibration of simply supported beam is discussed. The structural design and especially the real-time controls under forced vibration of the beam have certain practical values in engineering. |
