Abstract :Nonlinear oscillations of a mass with serial linear and nonlinear stiffness on a frictionless surface is considered. Equation of motion of the considered system is obtained. For analysing of the system, relatively new perturbation method that is named Multiple Scales Lindstedt Poincare (MSLP) and classical multiple scales (MS) methods are used. Both approximate solutions are compared with the numerical solutions for weakly and strongly nonlinear systems. For weakly nonlinear systems, both approximate solutions are in excellent agreement with numerical simulations. However, for strong nonlinearities, MS method is not give reliable results while MSLP method can provide acceptable solutions with numerical solutions.Keywords : Multiple Scales Lindstedt Poincare (MSLP) method, Nonlinear Oscillation, Nonlinear Stiffness, Perturbation Methods.
