灰色系统理论在混凝土侵彻深度计算中的应用

根据灰色关联分析原理,将影响侵彻深度的众多因素组成比较数列,将实际参数组成参考数列,由灰色优化理论得出选择侵彻深度计算公式的一般方法。经算例验证,这种方法的决策结果与实验结果相一致,侵彻深度计算误差小于5%,在工程中是可行的。

Application of Gray System Theory to Determination of Depth Calculation of Projectiles Penetration into Concrete

Based on a great deal of test data,all empirical formulas for projectiles penetration into concrete have a limited domain in engineering.According to the principle of gray correlation analysis,a comparison data sequences are composed of multiply factors that influence the penetration depth.Meanwhile,the reference data sequences are also organized by the actual parameters.A common method for choosing the empirical formula of penetration depth is presented based on the model of gray optimal theory.The results of example show that the result of the gray correlation analysis is consistent with the experiment result,and the error of penetration depth is less than 5%.
