Study on Band Gap Structure of One Dimensional Phononic Crystals Wang Yan-Lin1, a, Chen Ming-Wen2, b *, Wang Zi-Dong1, c * 1School of Materials Science & Engineering, University of Science & Technology Beijing, Beijing 100083, China 2School of Applied Science, University of Science & Technology Beijing, Beijing 100083, China aWYL1921@yahoo.com.cn, bchenmw@ustb.edu.cn, cwangzd@mater.ustb.edu.cn Keywords: Equivalent masses method; phononic crystal; band gap structure Abstract.
By changing a certain material component parameter or structural parameter respectively we analyze the vibration band gap structure under ensuring the density of the material A is bigger than the material B.
The result is consistent with the numerical results, there has some difference among them, the main cause is that the result obtained by using numerical analysis based on the model is continuously connected among the different materials, and the experimental model is connected by using the screw connection method.
