摘要
惯性平台系统作为惯性坐标基准和测量装置,广泛应用于导弹、火箭等飞行器中,其精度直接影响飞行器的工作效率。惯性平台系统在工作过程中由于热问题造成较大精度损失,陀螺仪和加速度表在工作过程中会为系统带来一定的热问题,有必要就其温度场进行研究并进行相关热设计,以提高工作精度。目前国内外主要依靠经典传热理论,利用有限元方法对温度场进行分析;主要从温控、热平衡、热稳定等方面进行热设计,相关热设计方法有添加加热片、隔热片、设计风扇、改善材料等。文章较为完整地整合惯性平台温度场研究状况和热设计方法,为今后同类工作提供依据。
As an inertial reference and measuring device,inertial platform system is widely used in missiles,rockets and other aircraft,and its precision directly affects the efficiency of the aircraft.In the working process,the inertial platform system causes the greater precision loss due to the heat problem.The gyroscope and the accelerometer will bring a certain heat problem to the system during the working process.It is necessary to study the temperature field and carry out the related heat design to improve the working accuracy.At present,we mainly rely on the classical heat transfer theory,and use the finite element method to analyze the temperature field,mainly from the temperature control,heat balance,thermal stability and other aspects of thermal design,related thermal design methods include adding heating,insulation,design wind tunnel,improving materials and so on.This paper integrates the research status and design method of the temperature field of the inertial platform and provide a basis for similar work in the future.
