Abstract

Phononic crystals ( PCs) flexible mechanical arms are introduced to study the vibration characteristic. Two research models single PCs arm structure and two link PCs arm structure are considered . The finite periodic structures are established to describe the ideal PCs structure s . The finite element analysis shows that t he angle doesn’t influence the range of the band gaps BGs while it influences t he attenuation value of each BG T he more close to 90 degree gives more distinct BGs. For axial vibr ation s, the t wo link PCs arm structure has the advantage to enhanc e the attenuation effect..
