When the temperature changes, the material properties of the rolling bearing change, which in turn causes the dynamic model equation of the rolling bearing to change. Given the problem in that the conventional dynamic model equation does not consider temperature changes, but because temperature changes cause changes in material performance parameters resulting in differences between the dynamic simulation signals and the actual signals, this paper fully considers three factors, namely, the thermal expansion coefficient, the hardness value, and the friction coefficient. With the influence of temperature changes, a study on the mechanism of the symmetric mechanism-rolling bearing dynamic system considering the influence of temperature factors is proposed. First, combined with the material properties of the rolling bearing, the changes in thermal expansion coefficient, hardness value, and friction coefficient caused by temperature changes were analyzed. Second, the functional relationship expressions obtained above were substituted into the existing conventional dynamic model. Finally, the comprehensive functional relationship formula was substituted into the conventional dynamic model to obtain the rolling bearing dynamic model under temperature difference changes. By studying the mechanism of the symmetric mechanism-rolling bearing dynamic system that considers the influence of temperature factors, this method can undertake a more comprehensive consideration of the dynamic analysis research into rolling bearing fault diagnosis, thereby verifying the effectiveness of the method.<\/jats:p>","DOI":"10.3390\/sym15122166","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T06:01:07Z","timestamp":1701842467000},"page":"2166","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Mechanism Study of Symmetric Mechanism-Rolling Bearing Dynamic System Considering the Influence of Temperature Factor"],"prefix":"10.3390","volume":"15","author":[{"given":"Chengshi","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Inner Mongolia University of Science and Technology, Baotou 014010, China"},{"name":"Inner Mongolia Key Laboratory of Intelligent Diagnosis and Control of Mechatronic System, Baotou 014010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tongtong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Inner Mongolia University of Science and Technology, Baotou 014010, China"},{"name":"Inner Mongolia Key Laboratory of Intelligent Diagnosis and Control of Mechatronic System, Baotou 014010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanliang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Inner Mongolia University of Science and Technology, Baotou 014010, China"},{"name":"Inner Mongolia Key Laboratory of Intelligent Diagnosis and Control of Mechatronic System, Baotou 014010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongliang","family":"He","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Inner Mongolia University of Science and Technology, Baotou 014010, China"},{"name":"Inner Mongolia Key Laboratory of Intelligent Diagnosis and Control of Mechatronic System, Baotou 014010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Inner Mongolia University of Science and Technology, Baotou 014010, China"},{"name":"Inner Mongolia Key Laboratory of Intelligent Diagnosis and Control of Mechatronic System, Baotou 014010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, X., Jin, W., Xu, X., and Yang, H.
