Optimal Design of Dampers of Complex Rotor-Support Systems

In this paper,the quasi\|component mode synthesis method is used to calculate a unbalance response of complex rotor\|support systems.The dampers are optimized to minimum unblance response and dynamic load of the supports.According to computation and test,a concept of optimal damping is presented.The optimal design can be done on a PC computer by program DOPTIM.By analysing a dual rotor system,it is shown that the theory,method and program developed in this paper are valuable for the design of rotating machineries.
