| Abstract: | A new kind of optimum design of uni layed global shell is introduced. Taking the overall cost as objective function, this optimum design is performed according to the requirements of specifications. It is a combination of the direct searching method and the criterion method. Based on the optimum design program with Fortran90 language, large quantities of computer calculation of uni layed global shell are performed. By the regress analysis, we can draw some optimal conclusions of the vector height, the number of lattice, the area of bar cross section and the volume of globe joint. The optimal result of the bar area is standardized so that it can be applied directly to practical engineering. |
| Keywords: | uni layed global shell optimum design regress analysis |
