Optimized Design of the Structure of High-Speed Railway Bearing Test Rig

Abstract:

This paper establishes the finite element model of main spindle in the test rig for high-speed railway bearing. Utilizing the finite element analysis software ANSYS, the modal analysis for spindle is carried on. Preliminary determination is that spindle resonance occurs. Structural optimization is carried out by increasing first natural frequency and reducing weight of main spindle in order to avoid resonance. The results showed that the position of support bearings is determined. The first natural frequency is increased by reducing spindle weight. The dynamic performance of the spindle is improved, avoiding the resonance region effectively.
