WebThe overall stiffness and condition number can be determined by evaluating the two eigenvalues, λ max and λ min, associated with this restrained stiffness matrix.The overall stiffness, given as the sum of the two eigenvalues or as k 11 + k 22, varies with the length as shown in Fig. 3.The condition number, computed as (λ max – λ min)/λ min, varies with …
Web5.1 Mass and Stiffness Fixes To avoid resonance, the forcing frequency applied to the structure should not be at or near a natural frequency. If the forcing frequency cannot be changed, then the natural frequency of the structure needs to be modified. This can only be done by altering the mass or stiffness (see Equation 1 ).
