INTRODUCTION
A torsional damper can be used to improve the vibration behaviour of shaft lines. However, this solution should be reserved for installations where direct adaptation of the stiffness and inertia distribution has not achieved the desired dynamic behavior. This article presents methods for pre-dimensioning tuned torsional dampers with elastic or viscoelastic coupling.
This article is part of a series on torsional rotor dynamics:
BM 5 120 Introduction ;
BM 5 121 Types of permanent excitations ;
BM 5 122 Inertia and stiffness distribution ;
BM 5 123 Analysis of operating conditions ;
BM 5 124 Study of torsion dampers.
