本文根据引信设计的需要,结合引信的结构特点,对截锥形弹以低速(200～500米/秒)和中速(500～1000米/秒)贯穿薄靶板(包括金属铝板和非金属的木质胶合板)时的动态特性进行了分析和计算。 在建立模型过程中,由于考虑了靶板强度效应的影响,解决了原来一些模型对低速冲击不适用的问题。并通过惯性效应和强度效应的比较,从理论上证明了Zaid和Paul的试验结论:即当冲击速度高于500米/秒时,可忽略强度的影响,而当冲击速度低于500米/秒时,不能忽略强度效应的影响。
According to the needs of fuze design and the structural characteristics of fuze, this paper analyzes the characteristics of fuze at low speed (200 ~ 500 m / s) and medium speed (500 ~ 1000 m / Of the wood plywood) when the dynamic characteristics were analyzed and calculated. In the process of model building, due to the influence of target intensity effect, some problems that the original model is not suitable for low velocity impact are solved. And through the comparison of inertia effect and strength effect, Zaid and Paul’s test conclusion is theoretically proved: when the impact velocity is higher than 500 m / s, the influence of the strength can be neglected; and when the impact velocity is lower than 500 m / s , You can not ignore the effect of the intensity effect.
