In Maximization of the First Eigenfrequencies is described how several lowest eigenfrequencies
are increased (figure below (b)) and Maximizing the Torsional Modal Eigenfrequency addresses how a specific eigenfrequency
in an eigenfrequency spectrum is optimized using mode tracking (figure
below (a)).
When maximizing the stiffness under
the condition that the first eigenfrequency is above 100 Hz or when minimizing
the mass under the condition that the eigenfrequencies are below or
above certain specified values, an eigenfrequency
can be applied in a constraint.
