| 摘 要： | 首先应用锤击激励法和LMS Test.Lab振动测试系统,对内部敷设黏弹性阻尼层的溜槽进行了模态试验,并以测点1为例说明了敷设不同厚度黏弹性材料对溜槽振动的影响。然后对敷设不同厚度黏弹性阻尼层的溜槽进行声学测试,发现敷设黏弹性材料越厚,溜槽的降噪效果越好。研究结果为敷设黏弹性阻尼层的溜槽的实际应用提供了参考依据。

| Abstract: | In the paper,hammer excitation method and the LMS test.Lab vibration test system are used to carry out modal testing for the chutes with viscoelastic damping liner.Firstly,it illustrates the vibration effect of the chutes with different thickness of viscoelastic material liner with test point 1 being served as example.After that,the paper makes the acoustics test to the chutes with differences thickness of viscoelastic damping liner,and finds that the thicker the viscoelastic material liner,the better the n... |
