摘　　要：以巡飞攻击导弹红外成像导引头为研究对象,从理论上对系统的半正弦波冲击响应进行了分析,给出了响应计算方法。建立了导引头有限元分析模型,利用ANSYS Workbench有限元分析软件,对导弹在发射及飞行过程中导引头需承受的发射冲击和分离冲击进行了分析计算,分析了导引头的应力、应变及探测器的加速度响应,计算结果表明导引头能承受住发射及分离过程的冲击激励作用。Based on imaging infrared seeker of loitering attack missiles, of half sine wave impact response were analyzed theoretically, impact response calculation method was given. The FEA model of the seeker was established with finite element software ANSYS Workbench. Computations of launch and separation impact response analysis of the seeker were carried out, stress and deformation of the seeker and acceleration response of the infrared detector were obtained. The calculation results show that the seeker can withstand the impact excitation of launch and separation process.
