摘要
:叙述用有限元计算方法对特定的机载计算机安装架进行结构强度计算 ,内容包括静强度计算、结构自由振动分析和波形为后峰锯齿波的冲击载荷作用下的冲击响应分析。计算结果对安装架的设计具有重要的指导意义。
This paper describes a structure strength computation of a certain mounting rack for airborne computer by the use of the finite element method. A static strength analysis,a free vibration and a shock response analysis have been completed. During the shock response analysis three final peak sawtooth shock pulses have been used. The computation results have an important guided meaning for the design of the mounting rack.
