First, the Gaussian random walk and adaptive parameter optimization algorithm for African vultures (GAVOA) is introduced into the algorithm. Second, GAVOA is used to optimize the penalty factor and modal component of VMD. This algorithm can effectively avoid the local optimal solution and improve the search efficiency. Finally, the feature vector is used as the input of CNN\u2010BiLSTM to identify the fault types of rolling bearings. The experimental results show that the GAVOA\u2010VMD\u2010CNN\u2010BiLSTM fault diagnosis model proposed in this paper has better performance, and the fault diagnosis accuracy can reach 99.667%.<\/jats:p>","DOI":"10.1155\/jece\/5650232","type":"journal-article","created":{"date-parts":[[2025,10,3]],"date-time":"2025-10-03T05:27:43Z","timestamp":1759469263000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Research on the Fault Diagnosis Method of Rolling Bearings Based on GAVOA\u2010VMD"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-2312-1945","authenticated-orcid":false,"given":"Jiaqi","family":"Xu","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5873-203X","authenticated-orcid":false,"given":"Yuanqi","family":"Xiao","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6195-3897","authenticated-orcid":false,"given":"Yipeng","family":"Yin","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5232-4006","authenticated-orcid":false,"given":"Yuxin","family":"Zhang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2025,10,2]]},"reference":[{"key":"e_1_2_16_1_2","doi-asserted-by":"publisher","DOI":"10.1088\/1757-899x\/225\/1\/012264"},{"key":"e_1_2_16_2_2","doi-asserted-by":"publisher","DOI":"10.1155\/jece\/5726510"},{"key":"e_1_2_16_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40430-024-04890-2"},{"key":"e_1_2_16_4_2","doi-asserted-by":"publisher","DOI":"10.1049\/joe.2018.9084"},{"key":"e_1_2_16_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2013.2288675"},{"key":"e_1_2_16_6_2","article-title":"Bearing Fault Diagnosis Based on Genetic Algorithm Parameter Optimization Based on Variational Mode Decomposition Combined with 1.5D Spectrum","volume":"38","author":"Bian J.","year":"2017","journal-title":"Propulsion Technology"},{"key":"e_1_2_16_7_2","doi-asserted-by":"publisher","DOI":"10.3390\/e23060762"},{"key":"e_1_2_16_8_2","doi-asserted-by":"crossref","unstructured":"ZhangY.
