Abstract：The problem of dynamic stability and bifurcation of submarine motion in the dive plane is examined utilizing numerical bifurcation tool box MATCONT based on Matlab .The signal parameter bifurcations analysis including submarine stern plane deflection and coordinates of submarine center of gravity are studied respectively .The saddle‐nod bifurcation and branch point are obtained ,and the stability analysis results are verified by direct numerical integration of the nonlinear equa‐tions .
