摘　　要：针对高精度光纤陀螺仪产品需在无明显气流的大尺度空间内进行批量检测的迫切问题,研究以辐射冷板为核心元件优化设计精密温控装置,并通过理论、模拟和实验的方法实现对该装置可靠性的验证。研究结果表明:优化设计效果显著,可实现检测空间范围内空间温度均匀性不大于2 ℃,24 h内温度波动不大于±0.05 ℃,温度扰动作用下温度场恢复时间不超过30 min;该优化研究解决检测环境温度控制中要求无风低波动的技术难题,突破传统技术路线中对检测空间的限制,实现高精度光纤陀螺仪在较大尺度空间的批量检测。The high-precision fiber optic gyroscope (FOG) products need to be tested in batches in a large-scale space without obvious air flow.For this purpose,the optimization design of precision temperature control device with radiation cold plate as the core element is studied,and the reliability of the device is verified by theoretical,simulation and experimental methods.The effect of optimization design is remarkable.The results show that the temperature uniformity is no more than 2 ℃,the temperature fluctuation is no more than ±0.05 ℃ within 24 hours,and the recovery time of temperature field is no more than 30 minutes under the effect of temperature fluctuation.The optimization research solves the technical problem of no wind and low fluctuation in the detection of ambient temperature control,breaks through the limitation of detection space in the traditional technical route,and realizes the batch detection of high-precision fiber optic gyroscopes in large scale space.
