摘要
本文分析了简谐激励下隔振系统振动功率流的极值特性。对于简谐激励而言,对应于基础阻抗和系统阻尼的改变,存在振动功率流的极大值,任何偏离该极值的改变都会使得振动功率流减小。阻尼因素对于振动功率流的影响,主要还是基于对共振状态的抑制作用。
The conjugate impedances and the damping in the vibrational power flow are investigated in this paper.There is maximum of vibrational power flow under harmonic excitation among the change range of foundation impedance and damping.The vibrational power flow will decrease for any deviation from the maximum point of isolation system.The influence of damping on power flow is mainly based on depressing the resonance.
