CN207758480U 一种利用三维准声子晶体减振降噪的车轮 失效 - 权利终止

一种利用三维准声子晶体减振降噪的车轮
摘要：
本实用新型公开了一种利用三维准声子晶体减振降噪的车轮，所述车轮包括轮毂、轮辋以及连接在所述轮毂与轮辋之间的辐板；所述辐板上安装有若干个三维准声子晶体；所述三维准声子晶体由至少两种声子晶体单元拼接构成。本实用新型的优点是：对于1000Hz以上的振动，车轮辐板处的三维准声子晶体具有弹性波禁带的特性，能够有效地抑制车轮辐板的振动，从而使得辐射的噪声得到控制；因此该车轮对1000Hz以上的中高频振动与噪声具有较好的减振降噪效果。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses an utilize three -dimensional accurate phonon crystal damping to fall wheel of making an uproar, the wheel includes wheel hub, rim and connects radials between wheel hub and the rim, install the three -dimensional accurate phonon crystal of a plurality of on the radials, three -dimensional accurate phonon crystal comprises at least two kinds phonon crystal unit concatenations. The utility model has the advantages that: to the vibration more than the 1000Hz, the three -dimensional accurate phonon crystal of wheel spoke plate department has the characteristic in elastic wave forbidden band, can restrain wheel spoke plate's vibration effectively to make the noise of radiation obtain control, consequently the well high -frequency vibration of this wheel more than to1000Hz has better damping and denoising effect with the noise.
