Previous research has mainly focused on the SPLs generated by traditional car models, with limited research on car frames and guide shoes. This paper constructs a structural model (CFS) based on conventional models, which includes a car, a car frame and guide shoes, to make the model more practical. The large Eddy simulation (LES) method simulates and analyzes the velocity amplitude and vorticity of the flow field around the CFS.\u00a0The asymmetric properties of the flow field are analyzed through the examination of velocity amplitude and the identification of instantaneous vortices within a wellbore airflow model. Then, using the Farassat\u2013Williams\u2013Hall (FW-H) method, the airflow-induced noise of different sound source surfaces (car frame, car and guide shoe) of CFS was simulated and compared with traditional models. Finally, the overall aerodynamic noise generated by CFS was analyzed. The results indicate that vortex shedding, airflow separation, and recombination around the car frame are critical factors in developing aerodynamic noise. The car frame\u2019s aerodynamic noise power spectral density is mainly concentrated at 5\u201350[Formula: see text]Hz, and the overall SPL generated by CFS is approximately linearly related to the logarithm of operating speed.<\/jats:p>","DOI":"10.1142\/s0218126625504043","type":"journal-article","created":{"date-parts":[[2025,7,8]],"date-time":"2025-07-08T04:59:21Z","timestamp":1751950761000},"source":"Crossref","is-referenced-by-count":0,"title":["Structural Modeling and Aerodynamic Noise Analysis of High-Speed Elevators Using LES and FW-H Methods"],"prefix":"10.1142","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3441-7370","authenticated-orcid":false,"given":"Wenqi","family":"Huang","sequence":"first","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Shandong Jianzhu University, Jinan 250101, Shandong, P.
