摘要: 为了研究弹载光电器件抗高过载机理,针对火炮发射环境特点,以某型特种弹所用弹载光电器件为例,建立了加装减载组件的弹载光电器件有限元分析模型并进行仿真分析。采用应力波理论,建立了反映弹载光电器件动力学过程的理论分析模型,计算求解作用于镜头的应力、相对位移和相对速度等,得到了弹载光电器件的动力学响应。结果表明:数值计算与仿真模拟结果有较好的一致性,验证了所建立的理论分析模型的正确性,可用于火炮发射环境下不同弹载器件的动态特性研究和抗高过载设计的理论分析。

Abstract: In order to study the anti-high-overload mechanism of projectile-borne optoelectronic devices, a numerical simulation model of projectile-borne opto- electronic devices is established according to the artillery launching environmental characteristics. A theoretical analysis model of projectile-borne optoelectronic devices is also established to solve the stress, strain and relative velocity of projectile-borne opto-electronic devices. The result shows that the numerically calculated results are in good agreement with the simulated results to verify the correctness of the theoretical analysis model. The proposed model can be used for the reseasch on the dynamic characteristics of the projectile-borne devicess and the theoretical analysis of anti-high-overload design.
