摘　　要：This paper represents an attempt at the application of catastrophe theory to the dynamic stability of engineering structures. The authors not only obtain a catastrophic model of vibrational buckling of elastic arches, but also give the critical condition of losing stability.This paper represents an attempt at the application of catastrophe theory to the dynamic stability of engineering structures.
