Lowest vibration mode Elastic buckling mode 0 1x/L The mode shapes correponding to (a) the lowest natural frequency, and (b) the elastic critical load, for a clamped-pinned axially-loaded beam. where: P is the magnitude of vibration force, L is the length of the beam, E is the stiffness of the beam, I is the moment of inertia, Xi are the characteristic functions representing the normal modes of vibration of the beam, βi are the magnification factors and kil are the roots of the system frequency equation that relate.

The upper layer is solely concerned with the process of fuzzy-tuning the boundary conditions of the flexible link. The rationale is to exploit the advantages, attributed to varying the boundary conditions of the compliant beam, in rendering the joint controller more effective .

The exact frequency at which a given vibration occurs is determined by the strengths of the bonds involved and the mass of the component atoms. For a more detailed discussion of these practice, infrared spectra do not normally display separate absorption signals for each of the 3n -6 fundame ntal vibrational modes of a molecule. The local modes are extracted out of the normal modes expressed in internal coordinates D nµcontribution of displacement q n to normal mode µ k µ force constant of normal mode µ N vib = 3N - 6 Elements µ of mode a n associated with internal coordinate q n a n Q.

This is the general equation for the transverse vibration of a uniform beam. beam varies harmonically with time, and can be written When a beam performs a normal mode of vibration the deflection at any point of the y = X (B, sin wt + B, cos wt), where X is a function of x which defines the beam shape of the normal mode of vibration.
