摘　　要：以HFCG160-140辊压机机架为研究对象,应用有限元分析软件COSMOS Works对辊压机整体机架进行有限元模态分析,得出了机架前6阶固有频率和相应的振型,分析表明机架不易发生共振,同时进行危险位置动应力与模态振动相关性分析和动应力变化幅频统计对比,机架上横梁中间处是振动强烈位置,对机架进行结构优化设计,对比优化前后振型和幅度,仿真分析结果表明优化能显著降低机架的振动幅度。HFCG160-140 Roller Press frame is used as the research object,.The finite element analysis software COSMOS Works is applied to the modal finite element analysis of the frame,the preceding 6 orders natural frequencies and the corresponding vibration modes of the frame are obtained,analysis showed that the occurrence of resonance frame is not easy and at the same time dangerous location,dynamic stress and vibration modal analysis and the relevance of changes in the dynamic stress amplitude and frequency statistical comparison,the middle of the beams is the strong position of the vibration and then optimize the design of the frame,compared the vibration mode and magnitude of before to after,simulation results indicated that it can significantly reduce the vibration of the frame.
