Based on the rigidity model of a linear ball guide incorporating the flexibility of the carriage,a modal analysis method was proposed by using finite element analysis. A three dimensional finite element model of a linear ball guide was established. The finite element modal analysis was conducted and the modal frequencies and vibration modes were presented. The modal testing experiment was conducted on the type of linear ball guide. For the occurrence of the modes, the finite element analysis results based on the presented method almost match with the experimental ones.
