某型号电控箱进行轻量化设计。给出了一种小体积、轻
质量、高稳定性电控箱的结构形式。针对遥感器电子学设备
在轨工作时的复杂工况，提出了一种电控箱防护性设计方法。对大功
耗元器件采取了主动热控措施。最后用有限元法对电控箱进行
了模态分析。结果表明，电控箱的一阶模态为240 Hz，远大于不
小于140 Hz的技术指标，能够满足空间应用的要求。 |

| Abstract:To meet the requirements of a
satellite platform, the lightweight design is needed
for a certain electronic control cabinet. The structure
style of a small, light and highly stable electronic
control cabinet is given. According to the complex operation
condition of electronic devices of remote sensors in orbit,
a protective design method for electronic control cabinets
is proposed. An active thermal control measure is taken for
high power consumption devices. Finally, the electronic control
cabinet is analyzed by using the Finite Element Method (FEM).
The result shows that the first-order modal of the electronic
control cabinet is 240 Hz which is much greater than the
specification of 140 Hz and can meet the requirements of
space application. |
