| 摘 要： | 针对传统设计方法设计的床身结构笨重的问题，以某型数控外圆磨床床身为例，在轻量化设计过程中提出一种尺寸优化策略，运用OptiStruct软件对床身结构的垫铁位置进行优化设计，在基于灵敏度分析对床身结构进行尺寸优化设计。优化结果表明，优化后床身的第一阶固有频率提高5.74%，重量减轻7.15%，验证了该尺寸优化策略在床身结构轻量化设计中的可行性及有效性。

| Abstract: | A typical bed structure of a cylindrical grinding machine is studied as an example in lightweight design, and a strategy divided into layers of sizing optimization is put forward. The pad iron layout is optimized as the first layer with OptiStruct with the second layer based on sensitivity analysis to optimize the size of bed structure. The optimized results show that the first natural frequency increases by 5.74% and the weight decreases by 7.15%, indicating that the strategy of sizing optimization is feasible and effective. |
