Lightweight Design of Centrifugal Compressor Baseplate Based on Topology Optimization
Baseplate of a large centrifugal compressor not only ensures structural rigidity and strength,but also requires light weight.ANSYS finite element analysis software package was used to complete the modal analysis of the centrifugal compressor baseplate.Based on the obtained natural frequencies of the first 6 orders and the corresponding vibration deformation data,the topological optimization of the support rib plate of the baseplate was carried out.After optimization,the first-order vibration frequency of the centrifugal compressor baseplate is similar to that before optimization,and the 20%resonance region frequency of the centrifugal compressor speed is reasonably avoided.The weight of the baseplate support rib plate is reduced by 30.7%,and the weight of the baseplate is reduced by 8.9%.The lightweight design is realized under the premise of ensuring that the rigidity and strength of the baseplate are sufficient.The study results have provided a theoretical reference for the design of centrifugal compressor baseplate,which aims at reducing cost and increasing effectiveness.
