This　study　focuses　on　applying　artificial　intelligence　techniques　to　virtually　simulate　the　vibration　characteristics　of　the　resonance　box　of　a　college　symphony　orchestra　to　improve　the　understanding　and　optimization　of　the　acoustic　performance　of　the　instrument.　The　study　uses　the　finite　element　method　and　digital　waveguide　technology　to　simulate　and　analyze　the　vibration　characteristics　of　the　stringed　resonating　musical　instrument,　which　is　realized　by　the　vibration　equation　of　an　ideal　string　and　the　principle　of　digital　waveguide　algorithm.　The　experimental　results　show　that　the　applied　simulation　technique　can　effectively　simulate　the　vibration　characteristics　of　the　resonance　box　of　the　musical　instrument,　such　as　the　ideal　string　vibration　and　the　cavity　coupling　effect.　In　addition,　the　study　involves　the　mathematical　expressions　of　forced　vibration　and　resonance　and　the　effects　of　various　materials　on　the　modal　frequencies　of　the　resonance　box.　The　application　of　artificial　intelligence　technology　in　studying　acoustic　characteristics　of　musical　instruments　significantly　improves　the　accuracy　and　efficiency　of　simulation.　It　provides　essential　theoretical　support　for　the　design　and　production　of　musical　instruments.
