Abstract EN
Numerical studies on the vibration and acoustic characteristics of a simply supported double-panel partition under the thermal environment are presented by the modal superposition approach and temperature field theory.
Many factors are considered in this theoretical research, including acoustic refraction, dynamic response of the panel under thermal and acoustic load, vibroacoustic coupling characteristic analysis, and the variation of material properties.
To access the accuracy and feasibility of the theoretical model, a finite element method is proposed to calculate the natural frequencies and mode shapes.
The results show that the vibration and acoustic responses change obviously with the change of thermal stress and material properties.
The rise of the graded thermal environment and thermal load decreases the natural frequencies and moves response peaks to the low-frequency range.
The first valley of sound transmission loss is well consistent with the mode frequency.
Finally, the relation between the average sound insulation and the thickness ratio is analyzed.
