The object of this paper is first to show the accuracy of the natural frequency for a straight beam\uff0c when the three-stress equation is taken as flexibility of the discrete vibration model. Secondly the coupled vibration of the beam is also treated by the same method. The three-stress equation coincides with the three-moment equation for the bending vibration and with the compatibility equation of the rotational angle for the torsion bending vibration. The bending moment M_r and the deflection y_r on the nodal point r are unknown values for the\u3000bending vibration\uff0cand the\u3000torsion bending moment B_r and the rotational angle \u03b8_r are for the torsion bending vibration. The equilibrium equation of the shearing force and the torsion bending moment at r\uff0cand two three-stress equations in which the inertia force and the inertia torque are put as equivalent concentrated ones at the node are corresponding to the four unknown values y_r\uff0c\u03b8_r, M_r and B_r\uff0cthus the natural frequency can be found from the matrix of the coefficients.
