A New Generation of Torsional Stress Analyzers for Turbine-Generators
Torsional stress analyzers (TSA) are used in power plants to monitor turboset shaft lines with respect to unallowable torsional stresses. This paper describes a new generation of these devices measuring torques at the shaft line directly at one or several points.
The principle design of the new TSA is explained, the basics of the mathematical procedure to calculate stresses and fatigue are laid down.
The advantages of this new development compared to those types already on the market are pointed out.
