چکیده:

One way for energy transportation of natural gas is by using the non-stationary cylindrical vessels moved with truck of trains. To design these vessels, because of the non-stationary conditions and positioning onthree of four saddle supports, the well-known standards cannot be used. To design these vessels , the stress in vessel components and deflection of vessels must be considered. In this paper , a method to determine the best position of saddles for getting the minimum deflection on the vessels in introduced using the finite element analysis (FEM) and the genetic algorithm . the method links FE software (ANSYS) with an optimization algorithm to get best position of saddle supports of vesselsin order to have minimum deflection of vessels . the constraints in optimization procedure consist of pressure vessels standards and local transportation lows. The results show that method can be effectively used for design optimization of CNG Pressure Vessels.
