| Abstract: | With the rapid
economic development of China, the express train and large
aircraft programs have generated huge social and economic
benefits. The optimal design of these high speed transportation
vechicles in the pursuit of lightweight and multi-functional
properties (e.g., stiffness, strength, heat dissipation, vibration
and noise control) has become a challenging problem, which needs
concerted efforts of researchers in various fields, including
solid/fluid mechanics, acoustics, mechanical engineering,
materials science and engineering and applied mathematics. Based
on our own studies, this article presents a comprehensive review
on the fabrication of various lightweight sandwich
materials/structures as well as the vibroacoustic characteristics
of lightweight sandwich materials/structures and corresponding
active/passive control techniques. Future research directions
regarding the vibroacoustic performances of lightweight sandwich
materials/structures are also discussed. |
