Torsional Vibration in shafts and other mechanical systems
The torsional vibration of a crank or motor shaft is an important factor in the suitability and reliability of a system design. Finite element modelling can predict the natural vibration and forced vibration based on the expected harmonics and speeds. However, modelling can only go so far, and oftentimes a measurement setup is required, such as ENSURE, for physical validation of the key assumptions.

Pumping and system pulsations are an important factor in the suitability and reliability of a design. Finite element modelling can predict the natural waves and forced waves based on the expected pump harmonics, geometries and speeds. However, modelling can only go so far, and oftentimes a measurement setup is required, such as ENSURE, for physical validation of the key assumptions.
Read MoreTorsional vibration has been known to fail the gear rotor of oil pumps. Typically, the failure occurs during testing on an engine dynamometer at the OEM’s facility. A failure at this point is not only very expensive and time consuming, but it also doesn’t look good for the reputation of the oil pump supplier.
