摘　　要：对转台关键部件进行了简化建模,利用有限元方法对其进行了动态特性分析,得出模型的固有频率及模态,并对结果进行了分析,得出振动影响该部件中光轴平行的因素,同时提出结构改进意见。The model of tumtable＇s key parts have been simplified. Its inherent frequency and model has been get by FEM method. The influence of vibration on light axis＇ parallel has been analyzed by using model＇s inherent frequency and model and giving the suggestion of promotion.
