| Abstract |
Spindle-bearing system plays a crucial role in superhigh speed grinding, which directly
affects machining precision, but it is complex and difficult to get the dynamic performance in
experiment. This leads to study how to accurately simulate dynamic performance of spindle-bearing
system. So a method which springs and damping units imitate bearing support is proposed in this
paper. The proposed method can predict the regular pattern which bearing stiffness and damping ratio
affect natural frequency and harmonic response. The research demonstrates that the method predicts
well the dynamic performance of the spindle-bearing system and it is close to actual condition,
therefore, it can be a reference for dynamic optimization design of spindle-bearing system in
superhigh speed grinding. |
