Abstract: By using coordinate and nearly,identical transformations.the strongly nonlinear Duffing system is reduced to normal form in this paper.and then the bifurcation equations with different resonant conditions and their solutions are obtained.The local bifurcation diagrams and the transition sets on unfolding parmeter and physical parameter plane are analysized by singularity theory. -
