摘要
高速精密轧辊磨头箱体是磨头的重要支撑部件,其结构刚度对保持内部各零件位置精度具有重要作用。为了提升磨头整体的抗振性能,采用拓扑优化的方法,对磨头箱体结构进行轻量化设计,并研究了不同筋板布局对其固有频率和刚度的影响。结果表明:拓扑优化方法可在保证磨头箱体静力学特性的前提下,尽可能减轻其质量;六种不同的筋板布局中,“米”字型筋板布局对提升箱体固有频率和刚度效果最为显著;拓扑优化方法调整了箱体的质量布局,有效提升了其动态性能。
The high-speed precision roll grinding head box is an important supporting part of the grinding head,and its structural rigidity plays an important role in maintaining the position accuracy of the internal parts.In order to improve the overall anti-vibration performance of the grinding head,the topology optimization method was adopted to lightly design the grinding head box structure,and the influence of different rib plate layout on its natural frequency and stiffness was studied.The results show that the topology optimization method can reduce the quality of the grinding head box as much as possible under the premise of ensuring the static mechanical properties of the grinding head.A study of six different ribbed layouts was carried out,and it is found that the layout of the“MI”shaped ribs is most effective in improving the natural frequency and stiffness of the box.The above method adjusts the quality layout of the cabinet and effectively improves its dynamic performance.
