Modal Analysis of Three Dimensional Numerical Control Laser Cutting Machine Based on Finite Element Method

摘要

In this paper, the three-dimensional CNC laser cutting machine as the research object, the finite element analysis software platform, using the related theories of modal superposition of the main moving parts of 3D CNC laser cutting machine for instantaneous modal analysis and the equipment of dynamic contact analysis; in structural design, should consider the modal of the fuselage beam etc. effect, avoid resonance.
