在低温和高温的外界环境下，探测器薄壁箱体容易出现高低温环境热胀冷缩引起的无规则变形，这对内部光学元器件的光路传递精度造成影响，进而影响探测器的探测精度。应用有限元方法建立探测器箱体热分析模型，运用 ABAQUS 软件对薄壁箱体进行高低温环境适应性分析，得到薄壁箱体在高低温环境下的应力和变形，并计算探测器光轴两端点之间因温度变化引起的偏转角度，在设计阶段对探测器的温度适应性能进行预测，减少设计人员以往基于经验而非科学原理设计产品的盲目性，降低样件试验考核成本。

Thin-walled box appears irregular deformation caused by thermal expansion and contraction when working in the low and high ambient.This affects optical path passing accuracy of the internal optical components,and thereby affect-ing the accuracy of the detector.Thermal analysis model of detector thin-walled box is established by finite element method. High and low temperature environmental adaptability of thin-wall box is analyzed by ABAQUS software to get stress and deformation under high and low temperature environment.The deflection angle between two endpoints in the optical axis of the detector due to temperature changes is calculated.Detector temperature adaptability is forecasted in the design stage, and it can reduce the blindness of designers designing products and the cost of sample test assessment.
