Piston–cylinder pairs are very common in industrial mechanisms. While a piston is primarily designed for axial reciprocating motion, the occurrence of secondary motions—lateral and rotational—due to the small clearance between the piston and th

Presented is a method to identify the projection of imbalance forces on high speed related modes of vibration, using data measured rotating at low rotating speeds. The method employs two actuators and several sensors to generate information not avail

The methods described allow one to directly measure the individual branches of the Campbell diagram of a physical gyroscopic system at any rotation speed. Typically, such data are acquired by exciting the vibration modes through naturally occurring u

Presented is a novel method allowing to perform mass balancing of flexible vibration modes, while rotating at low speeds. Through special external excitation, the projection of imbalance forces on vibration modes corresponding to high rotation speed

High-speed machinery is often designed to pass several $"$critical$"$ speeds, where vibration levels can be very high. To reduce vibrations, rotors usually undergo a mass balancing process, where the machine is rotated at its full speed range, during

The paper presents an improved slow-speed mass balancing procedure capable of reducing high-speed related imbalance. Parametric excitation is used to project the small imbalance forces onto a chosen mode of vibration, corresponding to a high critical
