摘要
分析某公司YBD-0立式加工中心的原始设计方案,在不降低其静动态特性的前提下,研究整机结构轻量化方案。首先分析计算了满载工况所需的切削力。然后将简化处理后的整机模型导入ANSYS Workbench开展静力学和模态分析,并对几个关键大件进行拓扑结构优化。最后对优化重建的整机开展静动态分析,对比了优化前后的整机性能。结果表明,优化后的整机质量和总位移分别为3361.66 kg和39.315μm,比优化前的3573.60 kg和60.864μm分别减少了5.98%和35.4%,基频由优化前的47.07 Hz提高到55.23 Hz,满足设计要求。
The original design scheme of YBD-0 vertical machining center of a company was studied to reduce its overall weight without reducing the static and dynamic characteristics.The cutting force required under full load condition was analyzed and calculated.Then,the simplified whole machine model was imported into the ANSYS Workbench for static and modal analysis,and several key large parts were optimized for topology.Finally,the static and dynamic analysis of the whole machine after optimization and reconstruction was carried out.The results show that the total mass and displacement of the whole machine after optimization are 3361.66 kg and 39.315μm respectively,which are 5.98% and 35.4% less than the 3573.60 kg and 60.864μm before optimization,and the fundamental frequency is increased from 47.07 Hz before optimization to 55.23 Hz,which can meet the design requirements.
