Vibration and Sound Transmission Characterization of TPMS Sandwich Panels
摘要
Abstract
Triple periodic minimal surface(TPMS)sandwich panels possess the advantages of light weight,large stiff-ness and high strength,and can be applied in ships,vehicles,aerospace and some other transportation fields.In addition,the panels need to have good vibration reduction and sound insulation performances to improve the comfort of the vehicle.In this paper,the acoustic-vibration theoretical model of TPMS sandwich panels was established based on Reissner's theory,and the acoustic-vibration equation was solved under the fluid-structure coupling condition.Numerical simulations were per-formed to validate the theoretical predictions.Based on the theoretical model,the effects of relative density,cell size and acoustic wave incidence angle on the vibration and sound transmission characteristic of TPMS sandwich panels were system-atically analyzed.The results show that the sound insulation of the sandwich structure can reach 85 dB in the frequency band of 20-5 000 Hz,and exceed 50 dB in the full frequency band.The structure parameters mainly affect the location of the sound insulation trough,and the incidence angle of the sound wave affects the overall sound insulation performance of the structure.The findings can be used as a reference for the engineering applications.关键词
