Journal bearing supported rotors present two kinds of self-excited vibrations: oil-whirl and oil-whip. The first one is commonly masked by the rotor unbalance, hence being rarely associated with instability problems. Oil-whip is a severe vibration wh

When a rotor operates in very low rotating speeds, the fluid-film in hydrodynamic bearings is not completely formed, which allows direct metal to metal contact between the bearing and the journal. Numerous start/stop cycles also may lead to bearing w

This work analyzes the influence of the wear in hydrodynamic bearings in the directional frequency response of a rotating system. Previous works presented a numerical approach to identify the bearing wear parameters using the unbalance response of th

Rotating machines present some common inherent operational problems, such as the critical amplitude of motion that the machine may experience when passing through one or more of its natural frequencies. High vibration levels can be harmful to the mac

In traditional modal balancing, a representative response of each mode to be balanced must be present in the measurement data. This is usually achieved by measuring the rotor response close to each critical speed corresponding to the modes of interes

Residual unbalance is the primary source of vibration in rotating machines. In many cases, the time and, consequently, the cost involved in the balancing procedure is high due to the need to accelerate the rotor up to every critical speed to be balan
