Torsional Analysis

Torsional Analysis is conducted for machine trains that are being purchased, modified, or have proved to be unreliable to evaluate the proximity of any torsional natural frequencies to excitation frequencies or evaluate the fatigue life of machines where torsional natural frequency interference is present.

Applicable Equipment

Torsional Analysis may be applied to all types of rotating or reciprocating machinery across a wide-range of industries. Kelm Engineering has conducted Torsional Analysis studies for compressor OEM’s, coupling manufacturers, end users with bad actors, and aftermarket repair facilities.

Benefits

Torsional Analysis should be considered for any new machine train and, like lateral Rotordynamic Analysis, is often cheap insurance when considering the cost of unreliability in critical applications.

How We Do It

Kelm Engineering, LLC uses the Finite Element based software DyRoBeS© from Eigen Technologies, Inc., as well as proprietary codes for Torsional Analysis and is capable of conducting detailed studies including:
