Simulation and experimental research on modal analysis for a new 5-axis superalloy blade machine tool

Abstract

This paper considers a new type of 5-axis machine tool which is used to cut superalloy blades specially.Referring to this new structure system, this study presents modal simulation in detail to calculate the structure vibration resistance. The modal simulation include building suitable finite element models, considering boundary constraints and interpreting results. The physical impact test of prototype is conducted to validate the simulation results. The modal simulation also reveals that some important partial characteristics that affects the structure performance are ignored in the physical test data. The validated model can be used to complement the experimental test.keywords: 5-axis machine tool, Finite element method, Modal analysis, Experimental test
