Abstract: This paper studied the location dimension A of the saddle supports of horizontal vessel. By using finite element method, the axial stress, tangential shear stress and circumferential stress of specific sections were calculated under different A values. According to the calculation results, the stress changes with A values were analyzed. Then the method of adjusting A values to reduce the stress in the specified range was summarized. This provides reference for supports locating of horizontal vessels.
