【Abstract】 In view of 850mm×250mm flat extruded cylinder, double prestressing force structure model is designed. The size of the model is designed based on 1/10 of the practical size. By finite element method, the stress is analyzed and the experiment of the model is simulated. The result is basically in accordance with the practical condition, which provides bases for the optimum designing of the structure of the flat extruded cylinder.更多还原
