MODAL ANALYSIS OF ROTATING MACHINERY STRUCTURES

Imperial College London University of London MODAL ANALYSIS OF ROTATING MACHINERY STRUCTURES by ENRIQUE SIMON GUTIERREZ-WING A thesis submitted to the University of London for the degree of Doctor of Philosophy Department of Mechanical Engineering Imperial College London September 2003 ii Abstract A new method for the MODAL characterisation of ROTATING MACHINERY STRUCTURES is presented. The method accounts for the effects of gyroscopic and other forces related to rotation, which are associated with the asymmetry of the damping and stiffness matrices of ROTATING MACHINERY . By comparison with other methods with the same feature, the new method has the advantage that it does not require the measurement of a complete row of the frequency response function (FRF) matrix. The new method is based on the modelling of ROTATING machines as structural assemblies of ROTATING and non- ROTATING components.

Modal analysis • is a method for solving for both transient and steady state responses of free and forced MDOF systems through analytical approaches. • Uses the orthogonality property of the modes to “decouple” the EOM breaking EOM into independent SDOF equations, which can be solved for response separately.

i.e., the j-modal damping ratio increases as the natural frequency increases. In other words, higher modes are increasingly more damped than lower modes. The response for each modal coordinate satisfying the modal Eqn. Mq Dq Kq Qj j jj jj j j n , 1,2... is obtained in the same way as for a single DOF system (See Handout 2).
