摘要：
Simple design criteria that determine whether the modal damping ratios of an underdamped linear lumped-parameter system are greater than, equal to, or less than a given non-negative real scalar are presented. The modal damping ratio expression is an extension of the usual single degree-of-freedom relation. The damping ratio conditions are derived from the modal damping ratio expression and the definiteness of certain combinations of coefficient matrices. An example illustrates how the damping ratio prediction relations are used in design.
