Dynamic Characteristic Analysis of the Spindle of Planer Drilling Machine Based on ANSYS

This paper elaborated the practical application of NC Planer Drilling Machine and the important consequence of main shaft structure to working qualities and working accuracy. Then it introduced the design proposal for the spindle structure of drilling machine. The static analysis, modal analysis and harmonic response analysis were done by using ANSYS. It lays a foundation for optimal design and remanufacturing.
