Most of the vibration analysis examples encountered in the previous chapters assumed that the inertial (mass), flexibility (spring), and dissipative (damping) characteristics could be “lumped” as a finite number of “discrete” elements. Such models are termed lumped-parameter or discreteparameter systems
. If all the mass elements move in the same direction, one has a one-dimensional system (i.e., “rectilinear” motion), with each mass having a single degree of freedom. If the masses
can move independently of each other, the number of degrees of freedom of such a one-dimensional system will be equal to the number of lumped masses, and will be finite.
