Abstract
In order to deal with the problem of low-frequency vibration and noise control in engineering, a new curved phononic crystal truss structure is constructed in this paper. The band gap characteristics are simulated by means of band structure analysis and vibration transmission analysis. Moreover, regulation rules of the band gap are analyzed. Numerical results demonstrate that through reasonable geometric parameter design and material distribution, a wide pseudo-band gap can be achieved. This curved phononic crystal truss structure can effectively suppress low-frequency vibration in both circumferential and radial directions.
期刊介绍:
Since 1965, the international journal Acta Mechanica has been among the leading journals in the field of theoretical and applied mechanics. In addition to the classical fields such as elasticity, plasticity, vibrations, rigid body dynamics, hydrodynamics, and gasdynamics, it also gives special attention to recently developed areas such as non-Newtonian fluid dynamics, micro/nano mechanics, smart materials and structures, and issues at the interface of mechanics and materials. The journal further publishes papers in such related fields as rheology, thermodynamics, and electromagnetic interactions with fluids and solids. In addition, articles in applied mathematics dealing with significant mechanics problems are also welcome.
