基于响应面优化法的套袋机构悬梁轻量化研究

Lightweight Research of Hanging Beam with Bagging Mechanism Based on Response Surface Optimization

利用SolidWorks建立悬梁模型并采用ANSYS Workbench软件进行静力分析。结果表明,悬梁的刚度与强度余量足够富裕,具有轻量化优化空间;以悬梁质量、变形为优化目标,应力小于等于屈服极限和设计变量取值范围为约束条件,采用Design Exploration优化工具的Box-Benhnken Design实验设计方法对悬梁进行尺寸优化。优化后,悬梁质量减少18.3%,节约了生产成本,且强度满足要求。为青贮机出料自动套袋机构悬梁结构及其他类似部件的优化提供了参照。

The suspension beam model was established using SolidWorks and the static analysis was carried out using ANSYS Workbench software.The results show that the stiffness and strength margin of the suspension beam is sufficient and has lightweight optimization space.Taking the quality,deformation and stress of the suspension beam as the optimization objectives,the Box-Benhnken Design method of the Design Exploration optimization tool was used to optimize the size of the suspension beam.After optimization,mass of the suspension beam was reduced by 16.31%,the production cost was saved,and the strength met the requirements.It provides a reference for the optimization of the suspension beam structure and other similar components of the automatic bagging mechanism of the foddermachine.
