To precisely forecast the vibrational response and stress subjected to acoustic excitation of a large satellite honeycomb sandwich plate, this article employs finite element modeling software to create a finite element model of satellite, equivalent honeycomb panels to orthotropic shear plates of identical stiffness and dimensions, and convert the acoustic excitation into random pressure on the surface of the flat plate, applying it to the surface of the satellite, then the vibration response and stress analysis subjected to acoustic excitation can be performed. The honeycomb structure collapsed after noise testing on a specific model of a large satellite, the aforementioned technique for response and stress validation was employed: the stress simulation analysis revealed that the maximum shear stress at the fracture site of the honeycomb panel was 0.45 MPa, exceeding the ultimate stress value of 0.44 MPa for the sparse honeycomb core at that location, leading to the collapse and fracture of the honeycomb panel. To resolve this matter, altering the honeycomb core design framework, a local dense honeycomb structure was implemented. The simulated shear stress of the honeycomb core is 0.54 MPa, which is below the stress limit of 2.43 MPa for the dense honeycomb core. To verify the feasibility of the plan, the noise test was conducted once again. Owing to the incapacity to test the shear stress of the honeycomb core, conducted strain testing on the surface of the honeycomb collapse and derive stress results by calculation, the test results deviate from the modeling values by 8.92%. And the maximum discrepancy between the simulated noise response and the experimental noise response is 0.58 g, validated the efficacy and precision of the simulation method, and successfully resolved the issue of damage to satellite honeycomb panels. This simulation method can precisely forecast the vibrational response and stress of satellites subjected to acoustic excitation.<\/jats:p>","DOI":"10.3390\/s25247444","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T15:30:07Z","timestamp":1765207807000},"page":"7444","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Vibrational Stress Analysis and Test Verification of Satellite Honeycomb Sandwich Plate Subjected to Acoustic Excitation"],"prefix":"10.3390","volume":"25","author":[{"given":"Liang","family":"Zhang","sequence":"first","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yousheng","family":"Shi","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanbo","family":"Chen","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangyu","family":"Zhao","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130000, China"},{"name":"Department of Precision Instrument, Tsinghua University, Beijing 100084, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jisong","family":"Yu","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Chang Guang Satellite Technology Co., Ltd., Changchun 130000, China"},{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2878","DOI":"10.1121\/1.411854","article-title":"Statistical energy analysis and structural fuzzy","volume":"97","author":"Lyon","year":"1998","journal-title":"J.
