| 目的 寻求注塑机前模板加强筋最佳设计参数。方法 在Pro/E和Ansys Workbench软件的协同环境下， 运用Pro/E参数-关系模块， 以注塑机前模板加强筋结构尺寸为设计参数， 建立前模板等质量模型， 并运用Workbench有限元静力学分析模块和参数设计模块,迅速计算出前模板力学参数在加强筋结构尺寸取一系列给定值时的对应值， 从而得到加强筋结构变化对目标变量的影响关系。最后从what-if分析中， 确定在设计变量取值范围内前模板最佳设计参数。结论 通过模拟试验得出， 优化后的模板与原始设计相比， 最大应力减小了10.9%， 最大变形也相应减小， 这为前模板的优化设计提供了模板加强筋的设计要点。 |

| This experiment aimed to seek the best design parameters of stiffening rib of injection molding machine′ s front mold plate. In the collaborative environment of Pre/E software and Ansys Workbench software, the Pro/E parameter-relationship module was used to establish the equi-mass model of front mold plate based on the design parameters of the stiffening rib structure size of injection molding machine′s front mold plate. Furthermore, the finite element static analysis module and the parameter design module of Workbench were used to rapidly calculate the corresponding data of mechanical parameters of front mold plate against a series of given values of the structure size of the stiffening rib, which revealed influencing relation of changes in stiffening rib structure on the target variable. Finally, the best design parameter of front mold plate was confirmed within the scope of design variable values by what-if analysis. Through simulation experiments, compared with the original design, the optimized one showed the maximum stress reduced by 10.9% and the maximum deformation decreased accordingly in the simulation test. |
