| Abstract: | Based on analysis of optimization in the structure of flat extruded cylinder, the model of flat extruded cylinder with local prepressed structure is designed and the results of finite element analysis of the model have been provided. Compared with flat extruded cylinder by means of equivalent thick cylinder, the flat extruded cylinder by means of local prepressure can make the equivalent stress on the dangerous part reduced by 30 percent under the equivalent condition. |
