基于ANSYS的高速吹灌旋一体机灌装系统组合机架结构优化

Structural Optimization of Filling Machine Frame of High Speed Blowing-Filling-Capping Combined Block Based on ANSYS

为了满足新型高速吹灌旋一体机可靠、低耗和轻量化的要求,同时为了降低新产品的成本,课题组对其组合机架进行优化。基于有限元分析软件ANSYS对原灌装机架进行应力和模态分析,结果表明机架的最大应力和最大变形均较小,机械强度远超设计要求。故课题组采用减薄底部法兰和矩形管厚度的方法对原组合机架进行轻量化改进。研究结果表明:改进后在保证机架满足强度要求的同时,不会发生共振,符合轻量化要求。课题组的研究降低了成本和能耗。

In view of the requirements of reliability,low consumption and light weight of the new high speed blowingfilling-capping combined block,and in order to reduce the cost of new products,the finite element analysis software ANSYS was used to analyze the stress and mode of the filling frame. It was found that the maximum stress and deformation of the frame were small,and the mechanical strength was far beyond the design requirements. Therefore,the method of reducing the thickness of the bottom flange and the rectangular tube was adopted. The results show that the method can reduce the cost and energy consumption,and achieve energy conservation and environmental protection,while ensuring the enough strength of the frame without resonance.
