摘要
针对注塑机肘杆式合模机构中模板要满足降低重量,提高强度、刚度及疲劳寿命的设计要求,应用ANSYS及FE-SAFE软件对某型号注塑机前模板进行了拓扑优化,从两个方向入手,即:对现行的结构再进行拓扑优化;回到原始的结构,并对其进行拓扑优化,寻求最合理的设计形式。对优化后的模板进行了应力、变形分析及疲劳分析,并对比了模板优化前后的应力、变形及疲劳情况。研究结果表明,优化后的模板模型质量更小,且最大应力更小、变形更小,具有更好的疲劳性能;通过应用ANSYS及FE-SAFE软件优化,注塑机前模板的强度、刚度、疲劳寿命及可靠度均得到了相应的提高,同时模型的质量减少,能够更加充分和合理地使用材料。
Aiming at the design requirements on inducing weight,improving strength,stiffness and fatigue life of the platen for the injection molding machine toggle clamp system,topology optimization on the front platen of the injector was carried out and proceeded with two aspects by using ANSYS and FE-SAFE software.One topology optimization was conducted with current structure,while the second with original structure in order to seek the most reasonable design form.The stress,deformation and fatigue properties of the optimized platen were analyzed.The results show that the optimized platen has less weight,lower stress and deformation,leading to the improvement of fatigue characteristics as compared to the platen without optimization.Moreover,the strength,stiffness and fatigue life of the platen of the injector are enhanced through optimizing by using ANSYS and FE-SAFE software.The results suggest that the material can be utilized effectively due to weight reduction of the front platen.
