Abstract

The phononic crystal (PC) has band gap characteristics, which can be used to design the band gap range by its microstructure, realizing the vibration suppression of specific frequency bands. Therefore, based on one-dimensional (1D) PCs, this paper proposes an approach to high-frequency vibration isolation for rod-shaped structures. First, the model of bipropellant rod-shaped structures of 1D PCs is established, and the transfer matrix method (TMM) of band gap calculation is introduced. Then, the characteristics of band gap and their influence factors are studied using TMM. And combined with the frequency response curves, effect of boundary conditions on finite bipropellant rod of 1D PCs is also studied. Last, taking the truss rod of support structure of space camera as an example, simulation is conducted. Results show that the proposed method is effective with great vibration suppression of 750-2000Hz, broadening the application prospects in other areas.
