摘要
利用有限元法对数控车床床身进行静力分析和模态分析,并根据分析的结果对床身进行了结构轻量化设计。结果表明,在保证床身刚度基本不变的情况下,通过调整床身孔结构和加强筋的厚度,将床身质量降低了6.27%,可有效地降低产品成本。
Based on finite element method,it analyzes the static characteristic and modal characteristic of CNC lathe bed,realizes the lightweight design for the bed structure. The results show that the bed in ensuring same stiffness,can be reduced 6. 27% by mass from adjusting the bed pore structure and thickness of the reinforcing ribs. This method may well reduce the cost of the product.
