一种大尺寸双冗余机载液晶显示器的设计

为了满足现代化大尺寸机载液晶显示器环境适应性以及可靠性的要求,采用了一体化大屏设计思想、双冗余设计方法以及特殊加固工艺技术,建立抗振动、冲击模型以及热力学仿真模型,通过ANSYS和FloTHERM仿真软件,获得机载液晶显示器各组件的应力分布以及温度分布情况。做了高低温、振动、冲击、湿热以及霉菌等国军标要求的相关实验后,得到机载液晶显示器抗振动、冲击以及热设计的重要方法和参考数据,并结合双冗余设计方法,使大尺寸机载液晶显示器能够满足军事领域使用要求。

A Kind of Double redundancy Design of a Big Size T FT LCD for Avionics

In order to meet the demands of reli-ability and ecology on a big size TFT LCD for a-vionics ,a integrative thought of design for a big size TFT LCD ,the method of double redundan-cy design and a special ruggedization technique will be adopted in the paper .Also ,establishing anti vi-bration and impact model and thermodynamics em-ulation model by ANSYS ,FloT HERM software , stress distributing and temperature distributing on the parts of TFT LCD for avionics will be ob-tained from the model .After experimentation of high and low temperature ,vibration and impact , wetness and mildew by domestic military standard ,＆nbsp;an important method and reference data for T FT LCD for avionics will be gained .Combined the method of double redundancy design ,a big size TFT LCD for avionics can meet the demand of military domain .
