It may be affected by earthquakes, winds, waves, and other loads in the working environment, causing changes in posture and affecting its sensing function. Therefore, it is of practical engineering significance to analyze the force conditions and posture changes in the bottom platform. In order to solve the problem of postural stability of the underwater bottom platform, this paper establishes a fluid and structural simulation model of the underwater bottom platform. First, computational fluid dynamics (CFD) technology is used to solve the velocity distribution and forces in the watershed around the bottom platform under a 3 kn ocean current, where the finite element method (FEM) numerical calculation method is used to solve the initial equilibrium state of the bottom platform after it is buried. On this basis, this paper calculates the forces on the bottom platform and the posture of the bottom platform at different burial depths under the action of ocean currents. Additionally, the effects of different burial depths on the maximum displacement, deflection angle, and postural stability of the bottom platform are studied. The calculation results show that when the burial depth is greater than 0.6 m, and the deflection angle of the bottom platform under the action of the 3 kn sea current is less than 5\u00b0, the bottom platform can maintain a stable posture. This paper could be used to characterize the postural stability of underwater bottom platforms at different burial depths for the application of underwater sensors in ocean engineering.<\/jats:p>","DOI":"10.3390\/s24103034","type":"journal-article","created":{"date-parts":[[2024,5,13]],"date-time":"2024-05-13T11:18:17Z","timestamp":1715599097000},"page":"3034","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Research on the Postural Stability of Underwater Bottom Platforms with Different Burial Depths"],"prefix":"10.3390","volume":"24","author":[{"given":"Yong","family":"Wei","sequence":"first","affiliation":[{"name":"Naval Submarine Academy, Qingdao 266199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nan","family":"Li","sequence":"additional","affiliation":[{"name":"Naval Submarine Academy, Qingdao 266199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Wu","sequence":"additional","affiliation":[{"name":"No. 710 Research Institute of China Shipbuilding Industry Corporation, Yichang 443003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daming","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Astronautics, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"108201","DOI":"10.1016\/j.engfailanal.2024.108201","article-title":"Failure mechanisms and seismic fragility analysis of overhead transmission lines incorporating pile-soil-structure interaction","volume":"160","author":"Liu","year":"2024","journal-title":"Eng.
