高速卧式加工中心床身结构模态优化设计研究

通过对高速卧式加工中心床身的结构、模态振型及振幅的分析,结合各参数在床身重要结合面处的灵敏度,设计了床身结构的综合优化方案。将优化后的模型再次导入ANSYS进行模态分析,并将工作台处及导轨处的最大振幅与优化前进行比较,结果表明,基于这种模态优化方法,床身工作台及导轨处最大振幅较优化前均明显减小。

Research on Modal Optimization Design of Bed Structure of High-speed Horizontal Machining Center

Based on the analysis of structure,modal vibration style and amplitude of the bed of high-speed horizontal machining center and combined with the sensitivity of the parameters at the important contact faces,a comprehensive optimization plan of the bed structure is designed.Then,the optimized model is imported into Ansys and a modal analysis is carried out.The maximum amplitude at the worktable and slideway is compared with that of the original model.The result indicates that the maximum amplitude of the opt...
