摘　　要：为了研究投影机系统的固有频率,通过Creo建立了投影机的三维模型,并且利用ANSYS Workbench计算出了投影机系统的固有频率。计算结果表明:投影机系统工作在安全频率范围内。该研究为投影机系统的设计及安装提供了理论指导。In order to study the inherent frequency of a projector system,the three-dimensional geometric model of the projector was established by Creo in this paper,and the inherent frequency of the projector system was calculated by ANSYS Workbench.The results show that the projector system works in safety frequency range.This paper provides the theoretical guidance for designing and installing of the projector system.

关 键 词：投影机 固有频率 模态分析
