摘要

It is always difficult to model the viscoelastic damping material accurately in a dynamics analysis, because the frequency has great influences on characters of the viscoelastic damping materials. This paper presents an iteration control program based on QR damping modal extraction method in ANSYS for calculating the structure modal damping ratio more accurately.
