| 中文摘要: |
| SRS冲击试验是一种应用较广的冲击试验方式，但是控制超差现象时有发生。以某次冲击试验实测波形数据为研究对象，建立了夹具处加速度激励与产品上制控点加速度响应之间的传递函数，将预测的冲击响应时域波形与实测时域波形对比分析，发现了SRS冲击试验存在显著的非线性，这种非线性是导致SRS冲击试验超差的主要因素。 |

| As a kind of shock environment test, SRS test is widely used. However, unexpected out of tolerance occurs in practice at times. Data of a certain SRS test were studied, and an acceleration transfer function of excitation in fixture and response in product control point was established. By means of comparing the predicted and practical shock response time-domain waves,remarkable non-linear property of SRS test was found, which was concluded to be the major factor of out of tolerance. |
