The object of this paper is first to show the accuracy of the natural frequency for a straight beam， 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　bending vibration，and the　torsion bending moment B_r and the rotational angle θ_r are for the torsion bending vibration. The equilibrium equation of the shearing force and the torsion bending moment at r，and 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，θ_r, M_r and B_r，thus the natural frequency can be found from the matrix of the coefficients. Numerical results are as follows : 　　(1)The method of the three-stress equation gives more accurate value than the method of the finite difference equation for M＝?Eiy^^・・ or B＝?EC_wθ^^・・.　　(2)When the radius of curvature R increases in the curved beam， the effect of the bending vibration increases and that of the torsion bending one inversely decreases","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"32083","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kimiteru, SADO","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"32084","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sumio, G.
