Abstract

Firstly, using CAD software SolidWorks to establish a geometric model of the servo turret. Then, using HyperMesh to pretreat the model. In the established finite element model the equivalent contact area method was used to simulate the bolt connection. At the same time, the virtual material method was used to equivalent bearing constraint. The equivalent contact area method effectively solve the nonlinear problems and improve the accuracy of bolt modeling. And the method of virtual material equivalent bearing constraints, the characteristics of the bearing was reflected more comprehensively. These two methods improve the quality of the finite element model and make the calculation results more accurately. Finally import the model to Abaqus for modal calculations. The first six natural frequencies of the servo CNC turret and its corresponding modal shapes are obtained in Abaqus. The results show that the servo turret has an adequate overall dynamic stiffness and no resonance phenomenon occurs. The modal analysis results provide theoretical basis for further harmonic response analysis and experimental modal tests. It can also indicate the direction of further improvement of the turret.
