Abstract
PAPER DESCRIBES a procedure for the dynamical design of linear vibration isolators to protect a rigid equipment from the sinusoidal motions of a nonrigid supporting structure. A single degree of translational freedom of the equipment is assumed.
Three types of data are required: (1) The equipment mass and its so-called fragility curve, (2) the mechanical admittance of the supporting structure and its amplitude of vibration when it supports no load, and (3) information to establish a minimum stiffness of the isolators.
The procedure yields a region of permissible natural frequency and fraction of critical damping combinations for the isolator-mass system. The specification for the isolator dynamical requirements, including allowable tolerances, is derived from this region.*
