Rotor Balancing Tutorial
normally on two correction planes near the ends of the rotor (near bearings) a. Check balance process will normally allow limited balance correction, since major corrections would have been completed during assembly b. “Large” corrections to an assembled rotor pose a nontrivial risk of vibration above the first critical speed due to

ME617 - Handout 7 (Undamped) Modal Analysis of MDOF Systems
rotorlab.tamu.eduIn MDOF systems, a natural state implies a certain configuration of shape taken by the system during motion. Moreover a MDOF system does not possess only ONE natural
Modal Analysis of MDOF Systems with Proportional Damping
rotorlab.tamu.edui.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).
