基于AWE的板材上料机多目标优化设计

The optimization design of the plate loading system by AWE

将有限元分析方法和优化设计理论相结合,以AWE软件为工具,对提出的板材上料机的末端执行器的重要部件——吸盘支架进行有限元仿真和优化。通过对超静定平衡方程的求解,获取了吸盘支架的载荷,并在AWE软件中作为边界条件对吸盘支架进行静态特性分析。在DOE模块中建立尺寸优化模型,以吸盘支架柔度最小、质量最轻为目标,以基体和压板的空间限制为约束条件,通过基于实验技术的多目标驱动优化方法,实现对吸盘支架尺寸参数的优化设计。最终获取了一种刚性、质量最优化的吸盘支架设计方案,并为板材上料机的尺寸优化提供了可靠的参考依据。

Combining the finite element analysis method with optimization design theory, a suction cups support framework, important part of end effectors of plate feeding mechanism designed,was simulated and optimized based on the tool of AWE software. The load of suction cups support framework was used as the boundary conditions on the static characteristic analysis for suction cups support framework in AWE, obtained by solving the statically indeterminate balance equation. Establishes the size optimiza- tion model in the DOE module, the minimum flexibility and the lightest weight selected as the goals. The space constraints of the matrix and board selected as constraint conditions, the multi-objective optimization method based on driving experiment technology adopted, and achieves the optimization design of size parameter. In the result, a design scheme of increasing rigidity and reducing mass drastically is achieved. It provides reliable references for the size optimization of the plate feeding mechanism.
