摘　　要：现阶段航天结构热试验的需求越来越大,而结构热试验造价高、风险大,且试验方法目前存在难以解决的弊端和难点,这就要求试验需要具备更高的技术能力以匹配新型号航天飞行器的研制。近年来,由于计算机辅助工程(CAE)技术的快速发展,虚拟试验技术成为验证产品热控设计的新手段。本文简要描述了通过对地面结构热试验的各个环节进行数字化建模,构建结构热试验虚拟试验系统的设计途径,系统各个模块组成闭环系统,用于各种结构热试验全流程的虚拟仿真。结构热试验虚拟试验系统的建立对结构热试验具有预示和指导作用,虚拟试验与仿真验证已成为缩短研制周期、降低项目风险和研制成本的主要途径。通过仿真试验与其他试验手段的结合,能有效地开展全系统性能试验。At present,the demand for structural thermal test of aerospace products is increasing,but the cost of structural thermal test is high,the risk is high,and the current thermal test methods are difficult to solve the drawbacks and difficulties.This requires the thermal test to have a higher technical ability to match the development of new aerospace products.In recent years,due to the rapid development of CAE technology,virtual test technology has become a new means to verify product thermal control design.This paper briefly describes the design approach of virtual test system for structural thermal test by digital modeling each link of the ground structure thermal test.Each module of the system forms a closed loop system,which is used for virtual simulation of the whole process of structural thermal test.The establishment of virtual test system for structural thermal test can predict and guide structural thermal test.Virtual test and simulation verification have become the main ways to shorten the development period,reduce the project risk and development cost.Through the combination of simulation and virtual test with other test methods,the whole system performance test can be carried out effectively.
