为了提供一个由温度变化导致压力舱压力变化的理论计算方法和依据，结合弹性力学和水力学理论基础知识，分析温度变化对压力舱试验压力的影响规律，建立温度变化与压降之间的关系式。通过具体实例，对温度变化引起压降进行量化分析。数据结果表明，理论计算和试验结果基本一致。
To provide a theoretical calculation method and basis for the pressure change of pressure chamber caused by temperature change. Firstly, combined with the basic knowledge of elasticity and hydraulics, the influence law of temperature change on the test pressure of pressure chamber is analyzed, and the relationship between temperature change and pressure drop is established. Then, the pressure drop caused by temperature change was quantitatively analyzed through specific examples. the data show that the theoretical calculation is basically consistent with the experimental results.
