| 摘 要： | 静力特性与动力特性是进行机床关键部件设计必须要考虑的重要方面.基于结构拓扑优化技术,本文建立了两种机床关键部件创新构型(结构形式)设计的数学模型,针对DLH20数控机床床鞍进行了创新设计,获得了新的设计方案.与原有设计方案相比,在质量减少3.34%的情况下,结构的静刚度得到了大幅改善,最大位移降低幅度超过了22%;结构的固有频率也得到不同程度的提高,最高增幅可达24.59%(第三阶固有频率).

| Abstract: | In the design of the key components of machine,static and dynamic characteristics are the important aspects to be considered.Based on structural topology optimization technology,two mathematical models was established in this paper to get an innovative configuration of saddle of DLH20 machine tool.CoMPared with the original design,the quality was reduced by 3.34%,in the mean time,the static stiffness of new design was increased substantially and the maximum difference exceeded 22%.In addition,the natural fr... |
