Original Abstract

In the paper the techniques of numerical inverse Laplace transforms (NILTs) are applied to get the time-domain responses of some classes of weakly nonlinear systems. It is enabled by expanding a response of the system into a Volterra series in connection with a multidimensional Laplace transform. For a given system the Volterra kernels transforms are found, and response Laplace transforms inverted numerically. This procedure avoids a necessity of the application of an association of variables technique. In the paper the method is demonstrated on the example of a simple second-order system while utilizing one and two-dimensional NILTs.
