Institution National Aerospace Laboratory NLR Date 1992-08-25 Abstract The Deterministic Power-Spectral-Density method can be derived from the Design Envelope Analysis of the continuous P.S.D.-method. It provides a method to determine a deterministic function that gives a maximum response equal to the P.S.D.-design load for linear systems. The P.S.D.-design load is undefined for nonlinear systems. In this report a "reasonable extrapolation" of the D.P.S.D.-method has been proposed for nonlinear systems. Design loads for a simple nonlinear aircraft model have been calculated. The results have been compared with results obtained with a "reasonable extrapolation" of the P.S.D.-method, using simulation.
