Abstract EN
In this work the critical pressure due to buckling was calculated numerically by using ANSYS15 for both stiffened and un-stiffened cylinder for various locations and installing types , strengthening of the cylinder causes a more significant increase in buckling pressures than non reinforced cylinder .
The optimum design of structure was done by using the ASYS15 program; in this step the number of design variables 21 DVs.
These variables are Independent variables that directly affect.
The design variables represented the thickness of the cylinder and( height and width of 10 stiffeners).
State variables (SVs), these variables are dependent variables that change as a result of changing the DVs and are necessary to constrain the design.
The objective function is the one variable in the optimization that needs to be minimized.
In this case the state variable is critical pressure (CP) and the objective function is the total (volume) of the structure.
The optimum weight of the structure with reasonable required conditions for multi types of structure was found.
The result shows the best location of stiffener at internal side with circumferential direction.
In this case the critical pressure can be increased about 18.6% and the total weight of the structure decreases to 15.8%.
