加固液晶显示器振动分析及抗振设计

Analysis and Anti-vibration Design on Rugged Liquid Crystal Display

从液晶显示屏的构造出发,分析了振动对液晶显示屏的影响,介绍了加固液晶显示器的抗振动加固方法。通过理论建模分析得出了相对位移响应均方值、绝对加速度响应均方值和系统固有频率的关系,运用该方法对一个工程实例进行分析,确定了系统的抗振设计参数,证明了该方法的有效性。

Starting from the structure of the liquid crystal display,this paper analyzes the impact of vibration on the LCD screen, and introduced the rugged technology on liquid crystal display. By theoretical modeling analysis, theresponse mean square valueof relative displacement and absolute acceleration is calculatedand the relationship with natural frequency is educed. An application example of project is given and the design parameters are determined, which prove the feasibility of this method.
