| 摘要: | 针对经验法确定吹塑制品壁厚尺寸而导致其力学性能过剩或不足、原材料浪费等问题, 通过使用响应面分析法和有限元分析法, 以吹塑制品质量最小、提升其力学性能为目标, 建立吹塑制品壁厚分布优化的数学模型, 对制品的壁厚分布组合进行研究; 在限定的目标条件内, 获取制品的最佳壁厚分布组合, 为研发过程中的壁厚尺寸提供选取标准. 研究结果表明, 通过响应面分析法与有限元分析法对吹塑制品的壁厚分布进行针对化的优化, 不仅可以提升制品的力学性能, 还可以降低制品的质量, 减少原材料的使用, 节约生产成本. |
| Abstract: | In order to solve the problems such as excessive or insufficient mechanical properties, waste of raw materials, and so on, caused by the empirical method of determining the wall thickness of blow molded products, this paper proposes a mathematical model by using response surface analysis and finite element analysis. The wall thickness distribution of the product is studied with the goal of minimizing the weight of blowing molded products and improving their mechanical properties. The best wall thickness distribution of the product within the limited target conditions is obtained and it provides reference of selection standard for the wall thickness size in the R&D stage of product development. The results showed that through response surface analysis and finite element analysis, the optimal wall thickness distribution of blow molded products can not only improve the mechanical properties of the products, but also reduce the weight of the products, and save the raw materials and the cost of production. |
