AI Technical Summary
In existing technologies, flanges are prone to weld cracking or warping deformation due to thermal stress concentration under high temperature and high pressure environments, and traditional damping components are not effective in dissipating energy at high temperatures.
A high-temperature resistant acoustic black hole vibration damping flange is designed, which integrates the acoustic black hole extension region and the rigid inner ring region, combined with mechanical damping components, to achieve wide-frequency vibration reduction through the ABH effect and release thermal stress at high temperatures.
It effectively prevents flange cracking or warping deformation, improves the energy dissipation efficiency of damping components at high temperatures, and achieves efficient wide-frequency vibration reduction and lightweight design of flanges.
