简述了制定QJ2483—93《固体火箭发动机静止试验动态参数数据处理方法》的必要性和实施时应注意的问题,着重对标准规定的动态校准方法、非平稳型随机数据的处理、频率响应函数的质量控制以及细化傅里叶分析和处理结果的不确定度等主要内容作了分析和简要说明。
This paper briefly introduces the necessity of developing QJ2483-93 “static parameter data processing method of static test of solid rocket motor” and the problems to be paid attention to when implementing it, and focuses on the dynamic calibration methods stipulated in the standard, the handling of nonstationary random data, the frequency response function The quality control and the refinement of the Fourier analysis and the uncertainty of the processing results were analyzed and briefly described.
