Study on Vibration Band Gap Characteristics of Phononic Crystal Consisted of Ti and Rubber

摘要

The vibration band gaps of one dimensional phononic crystal of rod structure consisted of Ti and Rubber were studied using the lumped-mass method and finite element simulation, the influences of vibration band gap by the periodicity and volume fraction were discussed. The results show that the initial frequency and cutoff frequency have little influence by the periodicity, but the anti-vibration effect is more effective as the periodicity increases; the cutoff frequency gradually decreases, the initial frequency decreases first and then increases as the volume fraction increases.
