摘要

为了提高加速度计在离心机试验中的试验效率和加速度计模型系数的辨识精度,针对离心机试验中加速度计高阶误差项的辨识精度问题提出了截尾D-最优设计方案,并与饱和D-最优试验计划进行了对比,结果表明采用本文提出的加速度计离心机试验的截尾D-最优试验计划,能够提高加速度计高阶模型项的辨识精度.%In order to enhance the experimental efficiency of accelerometer tested on centrifuge and to enhance the identification accuracy of accelerometer model coefficients, a truncated D - optimal design is proposed for the identification accuracy of the accelerometer 's higher - order terms.The truncated D - optimal design is compared with saturated D - optimal test plans.The results demonstrate that precision of accelerometer's higher - order terms could be enhanced by the method proposed.
