Abstract:The advanced conventional normal form method has only been used thus far in one or two dimensional systems and not yet in the study of multi-degree of freedom systems.In the paper, the normal form theory was extented to multi-degrees of freedom systems. The stable asymptotic solutions and limit cycles of strongly nonlinear oscillation systems with three-degrees of freedom and uncoupled in linear parts were investigated. The results testify the validity of the refined theory, which coincide with the solutions of numerical integration better than those of the initial normal form approach.
