摘　　要：分析了振动和高冲击对弹载制导电子系统不同的破坏机理.并且针对炮弹弹载制导系统的振动与冲击环境进行了抗振动与抗高过载冲击的结构设计.微型化电路结构设计提高了电子系统的固有频率,减小了共振引起的疲劳效应.灌封材料的应用和橡胶-泡沫铝交迭式隔振器设计,提高了系统的抗冲击能力.利用ANSYS软件对弹载制导系统进行了模态分析和瞬态冲击分析,获得了系统的固有频率、最大应力和最大位移.仿真结果验证了抗振动与抗高过载冲击设计方法的合理性.Vibration and high impact have different failure mechanisms for missile guidance electronic system,were discussed in this paper.According to vibration and impact environment of a artilleries＇ missile guidance system,anti-vibration and impact-resistance of structure were designed.Miniaturization circuit structure improved the electronic system＇s natural frequency,and reduced fatigue effect caused by resonance.Application of encapsulating material and the compound vibration isolator composed of rubber and foam aluminum improved the impact resistance capacity.Modal analysis and transient impact analysis of missile guidance system were processed to applying ANSYS software,and system＇s natural frequency,the maximum stress and maximum displacement were obtained.Simulation results show the rationality of this method which was designed to improve anti-vibration and impact resistance capacity.
