采用打靶法研究了离心场中纵向悬臂梁的大范围失稳与分岔问题．分析结果证实：随着参数ａ（离心臂长与梁长之比）的变化，梁平衡解可能发生三种分岔现象文中给出了平衡解的分岔形态，并发现了梁分岔解的单向跳跃现象，即突变现象。
The problem of large-scale instability and bifurcation of longitudinal cantilever in centrifugal field was studied by using shooting method. The results of the analysis confirm that three kinds of bifurcations may occur with the change of parameter a (the ratio of the length of the centrifugal arm to the length of the beam). The bifurcation of the equilibrium solution is given in the paper and the unidirectional Jump phenomenon, the phenomenon of mutation.
