投影机系统模态分析

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 re-sults show that the projector system works in safety frequency range .This paper provides the theoretical guidance for designing and installing of the projector system .
