• Unbalanced vibration and way of balancing of a flexible rotor supported at its both ends by members having any mechanical impedances are studied theoretically by aids of 'forced mode' method, and the results are further verified by experiments. Following facts are revealed and confirmed. (1) Vibration of the system can be expressed theoretically in a serial form, consisting of two parts of different natures. The one is the term influenced by dynamic character of the supports and the other coincides with that of 'simply supported' (i.e. supported by pinned-pinned ends) rotor. (2) If the rotor is balanced in 'simply supported' modes combined with dynamic balancing, the state of balance is maintained on any other supports having different mechanical impedances. (3) The rotor can be satisfactorily balanced only by measuring the vibration of the shaft and bearings at a speed, without knowing mechanical properties of the supports.
