Analysis and Simulation of Trunnion-type Numerical Control Rotary Table

Abstract

The combination of trunnion type numerical control rotary table and three-axis machine tools can achieve the work of five-axis machine center. The key part of trunnion-type numerical control rotary table, trunnion, was studied by statics analysis, modal analysis and harmonic response analysis. The maximum deformation, vibration performance and other parameters, which may do harm to the accuracy, were investigated. Meanwhile, the dynamics and kinematics analyses of rotary table virtual prototype were conducted. The results of simulation and analyses provide theoretical basis and important references for the optimization design and manufacturing.
