Abstract
The parametric characteristic analysis given in this chapter is to reveal how the parameters of interest in a separable parameterized function series or polynomial affect the function series or polynomial and what the possible effects are. This can provide a novel and convenient approach to investigate nonlinear effect incurred by different type and degree of nonlinearities in frequency response functions of nonlinear systems. Using this method, the GFRF and nonlinear output spectrum can all be studied in a parametric way and eventually formulated into a more practical form for nonlinear analysis, design and optimization in the frequency domain.
