| Abstract: |
| 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. |
