平头弹 meaning in Chinese

flat nose

In the experiment , two kinds of tubes with alternative diameters and material properties , and three kinds of flat - nosed cylindrical missiles with same length and various diameters are applied . two classes including six operating modes are designed in the experiment
在实验方面，本文采用了两种不同直径和材质的薄壁管试件以及三种长度相同，直径不同的平头弹体，设计了两大类六种工况下的实验。
A theoretical analysis of local damage in a thin ductile tube hit by a flat - nosed missile laterally is developed to predict local failure due to plugging by the beam - on - foundation model . the effect of internal press was considered , and differential equations was obtained which can predict the ballistic speed of the missile which impact the tube filled with water . it can be solved by runge - kutta method
采用地基梁模型对平头弹体侧向冲击钢管的冲塞型破坏模式进行了理论分析，考虑了充压情形下内压的影响，导出了钢管在冲击过程中的运动方程，可以用龙格?库塔法进行数值求解来确定弹体冲击充液压力管道的弹道极限速度。
