模态分析在航天电子产品结构设计中的应用

Application of Mold Simulation Technology in Structural Design of Space Electronic Equipment

在航天电子产品的结构设计中,设计选型阶段电路板等初始方案的选择,将决定产品最终的振动属性。常规的模态分析仅作为结构设计的一种检验手段,试图在设计之初便利用模态分析来指导初始方案的选择,进而改进航天电子产品的结构设计流程。

Generally,Modal frequency and modal characteristics of space electronic equipment lie in the foremost input,the mode simulation technology is used to be a way to check the structure design.This paper tries to use ANSYS software to solve the problem of structural design of space electronic equipment.Different kinds of structure or different structural dimension can draw different mode.With these results we can find out the best structure,which not only can be the input of PCB design,but also can give us the reliable way to begin the whole structure design.So the mold simulation technology can be applied to the structural design of space electronic equipment.
