泳池升降平台钢架结构的优化设计

针对传统泳池占地面积大、功能单一的问题,将升降平台技术应用到泳池设计中,提出了一种高度可调,满足不同人群诸如跳水、健康恢复、比赛等功能需求的新型泳池。开展了升降平台钢架结构最大应力、变形量和总质量的变化趋势分析,建立了钢架结构矩形管截面尺寸和上述参数的关系。提出了CAD/CAE协同设计的方法,使用Solid Works软件建立了升降平台钢架结构三维模型,并以Parasolid格式导入到ANSYS Workbench中。在ANSYS Workbench软件平台上,对矩形管截面尺寸的参数敏感度及输入参数响应进行了评价。使用目标优化法(GDO)进行了升降平台钢架结构的结构优化。结果表明,矩形管截面尺寸为30 mm×30 mm×4.5 mm时钢架结构最优。

Optimization for moveable platform of swimming pool

Aiming at solving the problems of large land occupation and single function of the traditional swimming pool, the technology of the moveable platform was applied to the design of the swimming pool. A new type of swimming pool the height of which is adjustable was raised. The swimming pool has many functions, such as diving, health recovery, competition and so on. After the analysis of the maximum equiva-lent stress, total deformation and total mass of the steel structure, the relationship between the section size of the rectangular tube and param-eters above was established. The method of CAD/CAE collaborative design was presented to the design of the steel structure. The three-di-mensional model of the steel structure for the moveable platform was built by the software SolidWorks and the model was imported to the soft-ware ANSYS Workbench by the format of Parasolid. The parameter sensitivity and input parameter response were evaluated on the software platform of ANSYS Workbench. The method of goal driven optimization( GDO) was applied to the optimal design of the steel structure. The results indicate that when the section size of the rectangular tube is 30 mm × 30 mm × 4. 5 mm the steel structure is the best.
