摘要
为满足高速、超高速加工对机床移动工作台轻质高动态性能的要求,设计了以铸铁为面板、泡沫铝为芯体材料的夹芯结构移动工作台,并利用有限元分析软件研究了该工作台的静、动态特性。研究结果表明与传统铸铁材料工作台相比,泡沫铝夹芯结构移动工作台具有质量轻、固有频率高、谐振响应幅值低等特点,从而证明了泡沫铝夹芯结构工作台在高速、超高速加工中应用的可行性和优越性。
In order to meet the requirements of lightweight and high dynamic performance of moving table of machine tool during high and ultra-high speed processing, a sandwich structure moving table was designed by taking cast iron as panel and aluminum foam as core body. The finite element analysis software was applied to study the static and dynamic characteristics of the table. The result indicates aluminum foam sandwich structure table is featured with lightweight, high inherent frequency low resonant response ampli- tude and etc. compared with that of table made of cast iron. So, aluminum foam sandwich structure table is effective and feasible in the application of ultra-high speed processing.
