摘　　要：该文将正交设计和D最优设计的理论应用于动调陀螺的位置测试中。根据回归模型,采用最小二乘法,并在D最优的准则下进行了动力调谐陀螺仪(DTG)测试试验方案设计,文中给出了具体的最优6、8和12位置的设计方案。通过对各设计方案的信息阵的数据分析可知,最优8位置比传统8位置的设计要好,且8和12位置的方案比其他位置的方案好。为了验证设计出的最优方案,我们进行了6、8、12位置及传统8位置的实验,对实验数据进行方差分析后所得结论与理论分析一致。The orthogonal design and D optimal design was applied to DTG position test. According to regression model, DTG test plans using the least squares method and D optimal rule was designed. The detailed optimal test schemes of six-position, eight-position and twelve-position was presented. The results indicated that the Optimal eght-position design was better than the traditional eight-position design through the data analysis of the information matrix of the test schemes. And eight-position scheme and twelve-position scheme are better than others. In order to verify designed optimal schemes, experiments of six-position, eight-position, twelve-position and traditional eight-po- sition was done. The conclusions using variance analysis on experimental data were in keeping with the results of theoretical analysis.
