Taking the typical missile-borne antenna module as the research object,the thermal deformation simulation and prediction model of the missile-borne antenna module is established by using ABAQUS software.At the same time,under the same conditions,the thermal deformation measurement system based on digital image correlation(DIC)method is used to extract and calculate the thermal deformation of the parts before and after changing temperature,in order to verify the accuracy of the thermal deformation simulation model.The results show that the simulation results of ABAQUS are in good agreement with the thermal deformation results measured by DIC method,and it is verified that the established finite element simulation model can evaluate the thermal deformation of parts accurately and effectively.
