Simulation Analysis on Dynamic Performance of Drilling Shaft Mechanism in PCB CNC Drilling Machine
The development of PCB CNC drilling machine is toward high-precision and high-speed, and the impact of the join cannot be ignored. Based on the finite element software, the finite element model of the drilling shaft system including the joins is established; the modal analysis and the frequency response analysis are performed on the drilling shaft system, the natural frequencies and mode shapes are obtained; the effect of the different parameters on the natural frequencies is analyzed, and the basic data can be obtained from the analysis.
