摘要
利用环境工程剪裁技术对某冲击试验的结果进行分析,结果表明,按照引用标准评定为"超差"的试验,当考虑到试验件结构的特性并进行必要的数据转换后,试验结果是有效。首先分析造成超差的原因为天线组件的剩余响应,然后通过频域数字滤波进行数据转换。
Result of certain shock test was analyzed with tailoring technology of environment engineering. The test was assessed to error according to reference criteria, if considered structure characteristic of test item and after essential data transition, then the result was valid. In this paper, we firstly educed that residual response of antenna subcomponent was the cause of error, and then processed data transition with digital filter in the frequency domain.
