• This paper presents an approach to finding optimum parameters of vibration isolators for systems subjected to stationary random force and/or foundation motion excitations. The vibration isolators to be determined consist of linear passive elements. Performance indices for the systems are expressed as nonlinear functions of the parameters of the vibration isolators. The optimum seeking method in nonlinear programming is applied to the determination of the optimum values of the parameters. The approach proposed in this paper is more versatile than the other approaches such as graphical technique using the trade-off curve. The procedure is illustrated on single- and two-degree-of-freedom systems with random excitations.
