| 摘 要： | 本文对带阻尼吸振块梁的自由振动作了理论研究。首先根据吸振块与梁的相互作用原理建立了计算力学模型,用 Laplace 变换方法求得了任意安置 n 个不同吸振块简支梁的复频率和复模态。最后给出了计算实例并进行了讨论。

| Abstract: | In this paper,the free vibration of beams stiffened with damping vibration absorbers are studied.The equationsof motion of the beam are introduced according to the beam-absorber interaction.Complex frequency equation andcomplex modal function of the beam,on which n-piece absorbers are arbitrarily fixed,can be found by means ofLaplace transformation method.Finally,some computer examples are given and are discussed. |
