为了解决潜射导弹水中段横向载荷在各种因素作用下难以建模计算的问题,采用灰色理论的分析方法,建立了适合折椅问题的GM(1,1)模型,并给出了算法运用的具体步骤。数据验证表明,所建立的模型不但能够较好的模拟使用过的试验数据,而且对于未曾接触的试验数据也具有很高的预测精度,有效的解决了导弹水中段横向载荷的计算。 In order to solve the problem that the lateral load of submarine-launched missile is difficult to be modeled and calculated under various factors, a GM (1,1) model suitable for the chair-folding problem is established by using the gray theory analysis method. The algorithm is given The specific steps. The data validation shows that the established model not only can simulate the used test data well, but also has high prediction accuracy for experimental data without contact and effectively solves the calculation of transverse load in mid-section of the missile.
