Cumulants of stochastic response for a class of special nonholonomic systems

This paper studies the response cumulants for a kind of special nonholonomi c systems under non-Gaussian, delta-correlated excitations. We present a ne w methodology for formulating the equations governing the evolution of the response cumulants of the stochastic dynamic systems. The response cumulant differential equations (CDEs) derived can be used to calculate the respons e cumulants for both linear and nonlinear systems. One example is given to illustrate how to use the CDEs for calculating response cumulants.
