This paper examines the assembly of hydroelectric generator rotors and stators, introducing a spatial relative position monitoring system using multiple sensors. A dedicated position monitoring program is designed, and error sources within the system are thoroughly explored. Detailed error analysis and modeling reveal that verticality and angular errors significantly impact monitoring accuracy. To address this, two error control methods are proposed to effectively mitigate these issues, ensuring precise assembly of large components.<\/jats:p>","DOI":"10.3390\/s24185992","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T11:36:37Z","timestamp":1726486597000},"page":"5992","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Error Analysis and Modeling of a Large Component Assembly Monitoring System Based on Multi-Sensor Fusion"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4807-3765","authenticated-orcid":false,"given":"Zhenggang","family":"Guo","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Dalian University of Technology of China, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Dalian University of Technology of China, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tizhao","family":"Jiao","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Dalian University of Technology of China, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingqi","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Dalian University of Technology of China, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fu","family":"Chang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Dalian University of Technology of China, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"955","DOI":"10.1177\/09544054211063269","article-title":"Novel Application of Mapping Method from Small Displacement Torsor to Tolerance: Error Optimization Design of Assembly Parts","volume":"236","author":"Mu","year":"2022","journal-title":"Proc.
