| 摘 要： | 宽频带随机振动冲击噪声会激发结构许多谐振峰,利用粘弹阻尼技术隔振、减振和降噪是一项新的技术措施,尤其是对于宽带随机振动和噪声控制具有特殊效果。在实际减振、降噪工程设计中往往需要知道所选用材料的损耗因子,复模量E*的温度谱的测量已经有专门的论述和成熟的方法。根据一个具体的实验研究探讨频率域复模量的测量进而计算材料的损耗因子。

| Abstract: | The noise from Broad Band random vibration strike causes many syntony peak of structure.The insulating and reducing vibration and noise by viscoelastic damp material is a new technology measure.Especially there is special effect in controlling noise from Broad Ban vibration.The loss factor needs to be known in insulating and reducing vibration and noise.There are some successful methods and special discussions on complex modulus E* chart with temperature.The article offers an experimentation on complex modulus E* chart with frequency. |
