摘要
针对某型导弹参数测试装置需弹载、硬着陆回收的要求,本设计重点对回收式固态存储记录仪的抗高冲击性进行了深入研究。机械壳体采用经特殊热处理后的高强度35CrMnSiA材料,内部电路用环氧树脂灌封,有效地提高了存储记录仪的抗高冲击的能力。首先采用有限元软件ANSYS/LS DYNA对记录仪机械壳体模拟了冲击过程进行了仿真,然后对环氧树脂不同灌封工艺进行对比,并做了马歇特锤冲击试验,最终找到了最佳灌封工艺,使固态存储记录仪达到了最佳抗冲击能力。
According to the requirements of one parameter testing device must be installed within the missile and hard landing recovery.This design emphasises on the research of impact resistance of recycling type solid state-storage instrument.The mechanical shell was made by high-strengh 35CrMnSiA after special heat treatment,the internal circuit was sealed with epoxy resin which effectively improving the ability of high impact resistance of the storage instrument.First of all,an impact process simulation was applied to the recorder mechanical shell by finite element software ANSYS/LS DYNA.Then a comparison of different epoxy potting processes was made,and an impact test of horse’s hammer was done.At last,the best found out technique can make the solid-storage instrument to achieve the best impact resistance ability.
