Numerical solution of the Rayleigh equation in non-linear vibration is studied in this paper. The di erential equation is integrated on a particular interval (0; T p2 ) with the initial value condition, u = A i and du=dt = 0 at the time t = 0. The value T p2 is determined from the condition such tha

Abstract
The stable periodic motion, described by Rayleigh differential equation, is solved by using the Mathematica software system. We define rules computing the periods T, the magnitude A, the displacement u(t), and the velocity v(t) for prescribed perturbation parameter Ξ΅ and circular frequency Ο. These rules have been explored to find the period T, the magnitude A, and the reducing factor of the circular frequency Ξ±=2Ο/T with 10 correct digits after decimal point for Ο equal to 1 and the values of Ξ΅ in the range from 0.1 to 100. The displacement and the velocity are plotted for Ξ΅ equal to 0.1, 1, 10, and 100. Copyright Β© 2003 John Wiley & Sons, Ltd.
