| 摘 要： | 针对等静压设备的预应力钢丝缠绕缸体结构的缠绕方法、强度和稳定性理论,定义了一种基于等剪应力缠绕的预应力大型结构轻量化设计模型.结合工作内压为300MPa、缸体内径为500mm的缸体设计实例,利用多岛遗传算法成功地得到了最优化解.质量由传统设计的9.03t减轻到8.53t,减少了5.5%.经专家系统软件和有限元软件验证,方案符合结构强度、刚度条件,预紧态结构不屈服,设计不失稳,并满足内径尺寸大于500mm等设计要求,方案可行.分析表明,该优化模型合理,多岛遗传算法收敛效果好.该方法适用于大吨位、超高温超高压等静压设备的缸体缠绕结构优化问题.

| Abstract: | Based on the iso-shear stress theory a light-weight wire-winding prestressed working cylinder for isostatic pressing equipment was designed through application of the multi-island genetic algorithm.A light-weight design model was defined.The maximum inner pressure in the cylinder was 300 MPa and the minimum inner diameter was 500 mm.Within these specifications the weight of the design was minimized.The weight of the conventional design is 9.03 tons,and the weight of the optimized design is 8.53 tons,corresp... |
