基于响应面的框架式复材成型模具轻量化设计

针对框架式复合材料成型模具的轻量化设计,提出了一种基于响应面的优化方法。该方法将被优化的尺寸变量与优化目标分别作为输入与输出,通过灵敏度分析与试验设计等方法建立并拟合为对应的响应面模型,设定轻量化优化目标与约束条件后求解数学模型获得优化方案。通过将求解结果代入有限元模型计算比较验证该方案的准确性,并以某具体模具为例阐述了该方法的原理与过程。

Lightweight Design of Frame Molding Die for Composite Materials Based on Response Surface

Aiming at the lightweight design of the frame-type composite material forming mold, an optimization method based on response is proposed. This method takes the optimized size variables and optimization goals as input and output respectively, and establishes and fits corresponding approximate mathematical models through methods such as sensitivity analysis and test table design. After setting lightweight optimization goals and constraints, the problem is solved by the mathematical model and is used to obtain the optimal solution. Solution results are substituted into the finite element model for calculation and comparison to verify the accuracy of the solution. A specific mold is used as an example to illustrate the use of the method.
