摘要：

The dynamic buckling of the column subjected to axial impact has been discussed in this paper. The dominant equations of dynamic buckling of the column and the boundary conditions of the wave front are derived from Hamilton principle. The qualitative analysis on dominant equations shows that the value of dynamic parameter I sets the characteristics of solution, and when lambda < 0 the buckling of the column occurs. The dynamic buckling load under different boundary conditions can be obtained through directly spreading dominant equations containing twin-parameter, and the dynamic buckling load is basicly consistent with the experimental results.
