粘弹阻尼材料动态力学性能对传递函数影响的研究

Effect of the Dynamic Properties of Viscoelastic Damping Materials on Transmissibility

本文以复刚度模型为基础,采用材料动态力学性能测试系统和计算机系统研究了阻尼减振器动态力学性能对减振效果的影响,结果表明,在离散型阻尼系统中,刚频变化率S_f的大小和损耗因子随频率的变化对高频隔振效果均有较大影响,理想的阻尼材料应有较低的S_f值和几乎不随频率变化的较高的损耗因子。

The effect of dynamic properties of damping isolaters onvibration control application was studied based on the complex stiffnessmodel with MTS and computer system. The results Show that for spot dam-ping treatmet, the stability of loss factor with the change of frequency andthe value of S_? have much to do with isolation effect in high frequences.The ideal damping materials for spot damping treatment should be of lowervalue of S_f and high loss factor which is stable with the change of frequ-ency.
