Abstract

Passive isolation design is often done in a single axis fashion, while most applications have performance requirements in multiple degrees of freedom. Optimization of six by six transmissibility requires a thorough understanding of base disturbances, payload performance needs, envelope constraints, and mass/cost weighting. Singular value analysis of the disturbance to performance transfer function matrix in the frequency domain is shown to be effective in creating a single curve for multi-axis isolation performance. The various limitations to passive isolation are enumerated as constraints on the optimization process. Analysis and design optimization results are presented for the kinematic hexapod (six strut) mounting of a hypothetical commercial laser communication terminal payload.
