碩士 === 國立成功大學 === 機械工程學系專班 === 101 === In conventional design of the pressure vessel, the ASME design codes have been adopted for many years. These design criteria are set up based on the mechanics of materials associated with experimental works. At the end of last century, the using of finite element packages becomes more and more important in mechanical design. A stress analysis on the horizontal pressure vessel with different surrounding angles and pitches of supports is performed in this paper. The vessel is designed by CSMC (China Steel Machinery Corporation) according the ASME code. Before detail discussion, a simple cylindrical vessel connected with spherical shell is simulated to validate the accuracy of the stress analysis. After performing the finite element analysis on the structure, the results of displacements and stresses can be compared with those obtained from the codes. To evaluate the optimum design on the geometry and location of supports, the distribution of effective stress, hoop stress and axial stress will be examined graphically. The methodology developed in the paper provides a efficient guideline in structural design.
