Optimum vibroisolation systems were obtained for a sitting human operator subjected to stochastic vertical vibrations. Is was concluded that there exists a physically realizable optimum function phi(s), which describes the desired fibroisolation system (s = iomega). The theory for finding an optimum vibroisolation system was developed on the basis of a specific a priori criterion, and assuming, for input, random, ergodic vibrations given by power spectral densities of accelerations of the vibration base. Examples are given for human body models consisting of a mass, a linear or nonlinear spring, and a damper.
