摘　　要：为适应控制系统低成本、高集成发展趋势,光纤惯组趋于高集成一体化设计。然而,精密仪表和大量电子元器件的高度集成,造成惯组内热流密度大大增加,传统的热设计方法已经不能很好地解决这一问题。因此,基于VPX架构的集成光纤惯组,提出了一种温度补偿+强迫风冷+相变材料的复合热控设计方法。通过系统热仿真及地面试验验证,结果表明:所提方法可以将集成光纤惯组内台体温度控制在惯性仪表正常工作温度范围内,对系统高度集成设计具有一定的工程借鉴意义。In order to adapt to the development of low cost and high integration of control system,fiber optic IMU trends to be highly integrated design.However,due to the high integration of the precision instruments and a large number of electronic components,the heat flux in IMU increases greatly,the traditional thermal design method can’t solve the problem well.Based on the integrated optic fiber IMU of VPX architecture,a composite thermal control method is proposed,which includes temperature compensation,forced air cooling and phase change material.According to the thermal simulation and the ground test,the result showed that the temperature of the inner-platform of the integrated optic fiber IMU can be controlled within the normal operating temperature range of the inertial instrument.Therefore,the method demonstrated such an approach is possible for the highly integrated system design.
