摘　　要：利用ABAQUS软件对飞行器结构地面随机振动试验进行模拟,并将仿真结果与试验结果进行比较,两者基本相符,验证了仿真模型的正确性。并用经验证的仿真模型对飞行器飞行环境下的响应进行分析,得到飞行器结构在飞行环境下的应力及变形,这对飞行器结构动强度设计、设备安装设计等均有参考价值。In this study ABAQUS software is used to simulate the random vibration tests on flight vehicle structure.The results of the simulation are basically consistent with the test results,which verifies the correctness of the simulation model.The verified simulation model is used to analyze the response of the flight vehicle structure in flying environment,and the stress and deformation of the flight vehicle structure in flying environment are obtained.The results are of reference value to the dynamic strength design and the equipment installation design of flight vehicle structures.
