摘要
研究了简支梁在轴向载荷作用下固有频率与轴向载荷的关系,得出ω21-P是一条直线,ω1-P是抛物线的结论.讨论了轴向载荷对简支梁振动的影响,对梁的结构设计,特别是对强迫振动下的实时控制,在工程中具有一定的实用价值.
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.
