摘要

为研究长径比、着角、靶板厚度、弹丸截面形状对弹丸侵彻靶板的临界穿透速度的影响规律,利用有限元仿真技术,进行不同因素对钨合金长杆弹侵彻装甲钢临界穿透速度的单因素分析及正交优化设计,由仿真结果所得极差值分析上述因素影响,并确定钨合金长杆弹侵彻装甲钢的最低临界穿透速度。研究结果表明:长径比与临界穿透速度为负相关,靶板厚度、着角与临界穿透速度均为正相关,弹丸截面形状也会对临界穿透速度产生一定影响;4种影响因素由主到次序列为:弹丸长径比、靶板厚度、着角、弹丸截面形状;利用正交优化表所得极差值,综合分析最佳因素组合为长径比40、靶板厚度30 mm、着角0°、截面形状正方形,得到最低临界穿透速度545 m/s;有限元仿真技术结合正交优化分析,不仅极大的简化仿真次数,而且可深入研究各因素对临界穿透速度影响,能为后续相似研究提供参考价值。

Abstract

In order to study the law of influence of aspect ratio, angle, thickness of target plate and section shape of projectile on the critical penetration velocity of projectile penetrating the target plate, finite element simulation technology was used to carry out single factor analysis of different factors on the critical penetration velocity of tungsten alloy long rod projectile penetrating the armor steel. Through orthogonal optimization design, the range of simulation results was used. The minimum critical penetration velocity of tungsten alloy long rod projectile penetrating armor steel is determined by analyzing the influence factors. The results show that the ratio of length to diameter is negatively correlated with the critical penetration velocity, the thickness of the target plate and the angle of impact are positively correlated with the critical penetration velocity, and the cross-section shape of the projectile also has some influence on the critical penetration velocity. The main and secondary factors affecting the critical penetration velocity of the projectile are as follows: the ratio of the projectile to diameter, the thickness of the target plate, the angle of impact, and the shape of the projectile section. Using the range value obtained from the orthogonal optimization table, the optimal combination of factors is as follows: the ratio of the aspect to diameter is 40, the thickness of the target plate is 30 mm, the angle of impact is 0°, the section shape is square, and the minimum critical penetration velocity is 545 m/s. The simulation technology combined with orthogonal optimization to analyze the critical penetration velocity greatly simplifies the simulation times, and further studies on the influence of various factors on the critical penetration velocity can provide reference value for subsequent similar studies.
