Abstract

Linear rolling guide have widely used in precision machinery today, with significant advantages such as high precision, low traction and low wear. Research on the dynamic characteristics of precision linear rolling guide became very important for space applications due to the continuous improvement of the manufacturing level of high-precision equipment. The THK's RSR small precision guide is studied in this research. The model of guide joint is established by optimized tandem damping element with the finite element method to simulate the dynamic stiffness and ball mass of the guide joint. The analytical formula based on Hertzian contact theory is adopted in this research to obtain the dynamic parameters of the guide joint. Accomplishing the the dynamic simulation analysis of the precision guide based on the finite element method by MSC.Patran & Nastran software.
