从热传导和热弹性理论出发，得出轴对称金属薄板温度应变模型；利用ANSYS有限元计算分析软件分析金属薄板的热变形状态，并与建立的模型进行比对验证；搭建了基于CCD、计算机、激光光源的散斑干涉温度测量实验平台，以钢质薄板作为实验对象，记录不同温度下对应薄板热变形的散斑图像数据；得到了散斑干涉条纹与钢板热应变的对应关系，进而得到了温度与热应变的关系。通过理论分析和散斑干涉实验平台获得的实验数据验证表明，金属热变形温度测试技术方案可行，为兵器、航天领域振动、腐蚀等恶劣条件下的温度测试，提供了一种全新方案。

According to the theory of heat conduction and thermal elasticity,the displacement temperature model of axial symmetric metal sheet is attained. In order to analyze the reliability of mathematical models,the paper analyzes the thermal deformation of the sheet metal state and compares the validation of the mathematical model. The experiment platform of thermal deformation measurement of metal with Speckle Interference is built on the subject of steel sheet and the speckle image data corresponding with thermal deformation of sheet are recorded. So the relationship between deformation and temperature is attained under heating condition. It is feasible which is verified by the theoretical analysis and experimental platform of DSPI. It provides a new solution for the temperature test under the harsh conditions of vibration liberation.
