Reconstruction methods based on local strain information have been proven effective, yet the identification faces significant challenges due to variable thermal\u2013mechanical loads, interactions among structural components, and special boundary conditions. This paper proposes a deformation reconstruction strategy tailored for ITSs under combined thermal\u2013mechanical load scenarios wherein deformations of both the primary truss structures and the attached panel systems are investigated. The proposed approach utilizes Ko displacement theory as the core algorithm, while the least squares optimization method is employed to determine the integration with unknown initial values during the reconstruction process. Validation is conducted through diverse load scenarios, and the reconstruction results are evaluated using errors based on the root mean square. The result demonstrates that the proposed method can reconstruct deformations of truss structures under both mechanical and thermal loads. Furthermore, the optimization-based approach achieves accurate reconstructed results in the case of panels with two-point fixed boundary conditions. This study provides an effective strategy for in-orbit deformation reconstruction, addressing challenges posed by complex loads and structural configurations.<\/jats:p>","DOI":"10.3390\/s25020558","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T10:32:15Z","timestamp":1737369135000},"page":"558","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Deformation Reconstruction Strategy for Integrated Truss Structures Subjected to Thermal\u2013Mechanical Load"],"prefix":"10.3390","volume":"25","author":[{"given":"Zexing","family":"Yu","sequence":"first","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofei","family":"Ma","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jialong","family":"Zhu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dayu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonggang","family":"Xue","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengfei","family":"Huang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yichen","family":"Li","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Li","sequence":"additional","affiliation":[{"name":"Xi\u2019an Institute of Space Radio Technology, Xi\u2019an 710100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"207","DOI":"10.1016\/j.eng.2022.04.013","article-title":"Recent advances in space-deployable structures in China","volume":"17","author":"Ma","year":"2022","journal-title":"Engineering"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1038\/s44172-024-00223-2","article-title":"Design, modeling, and manufacturing of high strain composites for space deployable structures","volume":"3","author":"Ma","year":"2024","journal-title":"Commun.
