Abstract
When performing finite element analysis of mechanical devices, it is difficult to calculate including the linear motion guide because the analysis cost is huge. In this paper, two finite element analysis models considering the rigidity of the linear motion guide are proposed. One is an iterative calculation method that repeats the load distribution theory and FEM. The other is a direct calculation method using a non-linear spring that follows the rigidity obtained by load distribution analysis. As a result of verification experiments using a uniaxial table, it is confirmed that both analysis models can accurately predict the deformation of the table. In addition, the ratio of displacement derived from the linear motion guide is estimated from the comparison between the experiment and the analysis using the machining tools.Keywords
