Acoustic Analysis and Noise Reduction in Audi A3 Car Cabin
- Conducted acoustic analysis on Audi A3 using Ansys, reducing cabin sound pressure levels with absorption materials to combat structure-borne.
- Developed Audi A3 cabin using SolidWorks, performed a convergence study, optimizing mesh size from 0.2m to 0.05m, achieving accurate frequency results for non-zero modes.
- Identified the first three non-zero frequency modes, achieving frequencies of -286.78 Hz to 307.1 Hz, ensuring effective noise suppression.
- Conducted harmonic acoustic analysis, reducing structure-borne sound frequencies from 87.6Hz to 67.936Hz for the first mode with absorber materials.
- Validated analytical calculations, achieving natural frequency results within a small margin of error compared to FE analysis.
