Conditions for both cases will be derived. Moreover, one can find excitation vectors which certainly lead to pseudoresonance. Also, in

Nina Kullrichn is usually called resonance and it is characteristic for undamped and lightly damped vibrating systems. For multi-dof-systems there may exist not only one but possibly more resonance frequencies. Since the occurance of resonance in vibrating systems is undesirable, due to the large amplitudes, the

Nina Kullricharge displacements in vibrations are seldom desirable, indeed, just the opposite holds true. The engineer makes efforts to arrange the vibrating system so that its motion is kept within the vicinity of a prescribed reference motion. When this is the case, the equations of motion relative to this ref
