Abstract:

Shape memory materials were used as active disassembly unit of LCD frame and LCD frame was redesigned by using the method of ADSM. Active disassembly design principles of LCD frame were proposed. A mechanical analysis model of active disassembly unit was established. The layout position of active disassembly unit in the frame was simulated by ABAQUS,and optimal size and layout position of the active disassembly structure were determined. At last, the size, layout position and disassembly effect of active disassembly structure of LCD frame were verified by experiments. A theoretical reference is provided for the design of LCD active disassembly structure.

Key words: smart material, LCD, active disassembly, shape memory alloy, finite element analysis

摘要：

将形状记忆材料作为液晶显示器支架之间的主动拆卸单元,运用ADSM方法对液晶显示器支架进行了重新设计。提出了液晶显示器支架主动拆卸设计原则,建立了主动拆卸单元的力学分析模型,利用ABAQUS优化了主动拆卸单元在液晶显示器支架上的布置位置,确定了主动拆卸结构的最优尺寸及其在支架结构中的布置位置,通过实验对液晶显示器支架主动拆卸结构的尺寸、位置及拆卸效果进行了验证。
