基于随机骨料的混凝土模型抗侵彻性能模拟研究

Numerical Simulation on Penetration Behavior of Concrete Based on Random Aggregate

为了更好地研究混凝土靶体抗侵彻的力学性能,基于随机骨料模型,研究了混凝土抗卵形弹侵彻的力学性能。在前人的基础上,根据随机函数,提出随机骨料的生成和投放算法,通过MATLAB软件,生成了混凝土随机骨料模型和基于随机骨料的混凝土侵彻模型。通过软件LSDYNA对侵彻模型的计算分析,结果表明,此模型更加符合实际,与实验误差更小。

In order to study the performance of concrete penetration resistance,the resistance of ogive-nosed projectile penetration of concrete was studied on the basis of the random aggregate model.On the basis of previous studies,the generation and insertion algorithm of random aggregate was proposed according to the random function and the MATLAB software.Then,through the finite element software,the random aggregate model and the penetration model based on the random aggregate model were generated.The results show that this model is more in line with the actual facts and the error by comparing with experiment is smaller in LS-DYNA calculation analysis of the penetration model.
