This study conducted static mechanics analysis and modal analysis on the tuyere of a blast furnace air supply device,aiming to investigate its structural characteristics and vibration properties.In the static mechanics analysis,a numerical model of the tuyere was established using the finite element method,and static mechanics analysis was performed to determine the overall deformation and equivalent stress of the cylinder.For modal analysis,the natural frequencies of the first 20 modes of the tuyere were extracted,and a detailed analysis was conducted on the vibration frequency,mode shape,and amplitude of the first six modes.The research results indicate that the natural frequencies of the tuyere increase with mode order,exhibiting the random nature of undamped vibration.Additionally,a comprehensive analysis of the mode shapes and amplitudes of the first six modes was conducted.Through the static mechanics analysis and modal analysis conducted in this study,a deep understanding of the static and vibrational characteristics of the tuyere in the blast furnace air supply device was gained,providing references for further structural design and optimization.
