Existing research on engine noise has been predominantly confined to experimental investigations of noise generation mechanisms and sound pressure levels, leaving critical gaps in predictive modeling. To address this, this study employs a numerical methodology for analyzing transient flow fields within the combustion chamber, enabling systematic characterization of vibration-coupled noise phenomena. Leveraging this computational approach, we elucidate the spectral and directivity features of vibration-induced noise. Subsequently, parametric studies identify key factors governing vibrational and acoustic responses. The results demonstrate strong agreement between simulated noise profiles and prior experimental data, confirming the model's predictive capability. Notably, the acoustic radiation exhibits pronounced directionality, with dominant emissions concentrated in specific azimuthal orientations. Furthermore, the parametric analysis yields actionable insights for structural optimization, including recommendations for chamber design parameters. These findings provide a theoretical foundation for mitigating vibration and its resultant acoustic emissions, thereby supporting future advancements in the performance and durability of RDEs.<\/jats:p>","DOI":"10.1121\/10.0042234","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T13:06:13Z","timestamp":1768395973000},"page":"408-421","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Noise analysis and vibration control of flow-induced vibration in the rotating detonation combustor"],"prefix":"10.1121","volume":"159","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8475-5783","authenticated-orcid":false,"given":"Yuanyang","family":"Xu","sequence":"first","affiliation":[{"name":"Beijing University of Chemical Technology , Beijing 100029,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9805-2583","authenticated-orcid":false,"given":"Yuhui","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing University of Chemical Technology , Beijing 100029,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2026,1,14]]},"reference":[{"key":"2026011408060120400_c1","doi-asserted-by":"publisher","first-page":"345","DOI":"10.1007\/s42464-022-00180-5","article-title":"Nonlinear stress analysis of rubber-like thick-walled cylinder","volume":"25","year":"2022","journal-title":"J.
