摘　　要：提出数控机床大件结构设计元结构和基本框架的概念,把由床身筋板围成的栅格称为筋格,床身的宏观构形为基本框架:筋格的动态特性直接影响机床床身的动态特性。用有限元分析法对床身筋格结构动态特性进行研究,总结出对数控机床床身设计具有普遍指导意义的规律,可用于数控机床床身结构初步设计。The concepts 0f unit structures and basic frame for desig n of Nc mach ine tools main components are given .The unit 0f grids formed by the rib walls of machine tools bed is named rib box,and the shape of machine tools bed is nam ed basic frame.The dynamic characteristic 0f rib box directly effec ts dynamic c haracteristic of machine tools bed. By studyding zhe dynamic charac teristic of simplified machine tools rib box of bed with FEA,some useful laws in respect of dynamic optimal design of machine tools bed structure ale obtained,and these 1 aws can be used in primary design of NC machine tools bed structures.
