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. Introduction In recent years, machine tools need better properties, such as high speed, high precision, high efficiency and complex, to meet the high processing requirements [1-3]. The common machine tools fail to meet these demands. So five-axis machining center will lead the development trend of machine tools.
