Abstract
Madal performance is the basic characteristics of structures, which will help to further understand the vibration of structures. Besides, fluid (e.g. water) coupled with structure will strongly affact the modal performance of structure. To get clear the modal performance, Modal tests are conducted for two-layered plate both in air and in water, and modal frequency and mode shape are given. With comparative analysis of modal frequencies in these two cases, it’s shown that influence of fluid on structural vibration is obvious, which will results in significantly reduction of modal frequency, and the maximum reduction is the second mode, and it is more than 42%. But it’s also noted that influence of fluid on mode shape is little.
期刊介绍：
MATEC Web of Conferences is an Open Access publication series dedicated to archiving conference proceedings dealing with all fundamental and applied research aspects related to Materials science, Engineering and Chemistry. All engineering disciplines are covered by the aims and scope of the journal: civil, naval, mechanical, chemical, and electrical engineering as well as nanotechnology and metrology. The journal concerns also all materials in regard to their physical-chemical characterization, implementation, resistance in their environment… Other subdisciples of chemistry, such as analytical chemistry, petrochemistry, organic chemistry…, and even pharmacology, are also welcome. MATEC Web of Conferences offers a wide range of services from the organization of the submission of conference proceedings to the worldwide dissemination of the conference papers. It provides an efficient archiving solution, ensuring maximum exposure and wide indexing of scientific conference proceedings. Proceedings are published under the scientific responsibility of the conference editors.
