Vibration and noise characteristics base on timing silent chain system of hybrid electric vehicle
Based on the special working condition requirements of hybrid electric vehicles, this thesis conducted a study on the vibration and noise characteristics of the timing silent chain system (TSCS) based on the structural design of the TSCS. The dynamics characteristics of the TSCS were analyzed and the boundary conditions required for vibration analysis were obtained by establishing the dynamics model of the TSCS, and based on the finite element analysis method, the vibration of the TSCS was studied through modal analysis and frequency response analysis, at the same time, using the vibration characteristics of the TSCS as input conditions, the acoustic boundary element simulation analysis of the TSCS was carried out, and the acoustic pressure-frequency response curve and the distribution of noise were studied. The analysis results show the excellent vibration and noise characteristics of the TSCS, and the analysis method will provide a reference for the vibration and noise reduction work of hybrid electric vehicles.
