G3i电源站电路板跌落仿真分析

Drop test simulation of G3i-PSU PCB

G3i电源站中电路板损坏的原因大多因为运输或布线过程中的跌落或抛掷所致。应用仿真软件Ansys workbench对G3i电源站电路板进行跌落仿真分析,得到电路板跌落冲击后的受力和变形情况。参考分析结果并结合实际电路板的返修情况,针对电源站的壳体空间设计了电路板的保护装置。再将保护装置和电路板装配,在同样的条件下进行跌落仿真分析,对比前后分析结果能够证明保护装置起到了一定的保护作用。

PCB(Printed Circuit Board)of G3i-PSU(power supply unit)doesn’t work mostly due to falling down or being cast down during transportation and distribution of lines.We apply ANSYS workbench to calculate the stain and the deformation of PCB of G3i-PSU in drop test,which provides a reference for the shield design of PCB of G3i-PSU.Under the same conditions,drop test analysis is conducted again on PCB of G3i-PSU with the shield designed,whose results show,the shield designed can offer much protection for PCB of G3i-PSU against damage from dropping.
