Finite element analysis of problems in the modeling

More sparse, Figure 5 Angular unit density at the transition structure of the grid model data wrapped in the name of cranes landing craft base unit type diaphragm wall pull film, slab,[link widoczny dla zalogowanych], beam unit drum 97l1. 8ll982 freedom 3068354Bl383 running nodes 74,683,596 Time (s) 340037301Ol157 is deckhouse front wall of the main deck and the opening of the unit grid. Figure 8 is a hoard underground continuous wall retaining structure finite element model of half of the body. Simplified is the main analysis of the circular area, cell size smaller. The structures were calculated with the general structure analysis program. In the IBM-8081 machine is running, get more satisfactory results. Table Figure 8 landing craft ship finite element model of half of Figure 7, the main deck trellis openings cell wall of semi-continuous finite element model of 1 shows the model of their relevant data and run time. Fourth, the two mesh refinement calculation on the transition with finite element mesh density model to verify the results obtained with the convergence of the stress concentration value or a more detailed calculation of the stress gradient, usually from the body of law,[link widoczny dla zalogowanych], that is taken to checking site . And appropriate to relax the scale, would have been considered as displacement. From the body as a boundary condition, location and number of boundary nodes remain unchanged. Then mesh refinement calculation. This method is the boundary node from the body immobilized, the difficulty of bringing the grid to fine,[link widoczny dla zalogowanych], and the boundary nodes to the same question too complicated,[link widoczny dla zalogowanych], the remeshing and the computation is quite time consuming. An effective method is to use finite element analysis program of the shape function. Department should be checking on. Take only a very small part (the dry units), to split from the body along the border with the small mesh refinement, boundary nodes with the element shape function interpolation. As boundary conditions, plus the small portion of the structure taken are calculated by this method may need to constantly refine the calculations until convergence. Therefore, put less of the workload and machine, you can get better results. This method can also be used to fine-coarse grid computing.

As follows: Six, Conclusion The above brief description of chemical tankers structural design of the parties. Can be seen, although the development of chemical tankers are not historical power for too long, it has gone through several generations of change, and as more and more complex chemical liquid cargo safety of people and the importance of environmental pollution, transport of chemicals will ship design and construction of higher demand, which led to l compared with the norms and rules related to the development. Predictable, the modern chemical tankers for shipment will be a variety of chemicals can be, according to a highly complex operation of the ship but expensive. l temperature of base metal - 1 - A
