The single and double drive technologies for heavy NC rotary table were discussed. Based on mechanism analysis, the dynamics models of the single and double driving systems were established and simulated. The simulation results prove the superiority of double-drive technology.%介绍重型数控转台单、双驱技术的基本原理,基于机理分析建立了单、双驱系统的动力学模型并进行仿真分析,仿真结果证明了双驱技术的优越性.
