Structure optimization and performance analysis of a п-type double-supported high-speed countercurrent chromatography rotor system
摘要
Abstract
Rotor system is one of the core components of countercurrent chromatograph and plays a key role in the realization of high efficiency separation function of high-speed countercurrent chromatograph.In this pa-per,aiming at the problems such as heavy weight,easy fracture of unwinding tube and difficult disassembly in cantilever installation of countercurrent chromatograph under existing technology,we propose a п-shaped mechanical structure for the double-supported rotor system of countercurrent chromatograph.Static analysis and modal analysis are conducted by using the Ansys Workbench simulation platform.Then,based on the SIMP variable density method,topological optimization of the п-shaped double supported planetary frame is carried out with the improvement of structural stiffness as target and the reduction of mass as constraint.Fi-nally,dynamic and static mechanical performance analysis and fatigue analysis are conducted for the rotor sys-tem by secondary modeling,a prototype is trial-produced.Simulation results show that the rotor system after the optimization of planetary frame meets the design requirements of high-speed countercurrent chromato-graph with 11.9%lower mass.It is expected that the obtained results can help for the efficient separation per-formance of high-speed countercurrent chromatograph.关键词
