摘　　要：为了满足卫星平台的要求,需要对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。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.
