本文主要论述运用模型试验来研究车床床身的合理结构.文中简述了通过模型对比试验和应用激光全息干涉计量术来研究结构的变形状态;探讨结构的合理参数;寻求刚度高且工艺性也好的结构的情况.并根据对试验结果进行的理论分析和计算,论述了切应力对变形的影响.最后,对床身的侧壁、腹板、贴壁筋、裙边的作用进行了分析,为正确地设计床身结构提供了理论根据. This paper mainly discusses the use of model tests to study the rational structure of the lathe bed. This article briefly describes the model deformation test and the application of laser holographic interferometry to study the deformation state of the structure; explore the reasonable parameters of the structure; seek high rigidity and processability In the case of a good structure, and based on the theoretical analysis and calculation of the test results, the effect of shear stress on the deformation is discussed. Finally, the effect of the sidewalls, webs, ribs, and skirts on the bed is analyzed. , to provide a theoretical basis for the correct design of the bed structure.
