| Abstract: |
| Objective To apply laboratory comparison test to vibration laboratories. Methods Referring to the mature methods of measurement laboratory comparison, the features of vibration environmental laboratory and its difference from normal measurement laboratory were analyzed. Results It was pointed out that in normal measurement laboratories, the values measured were the objective attributes of the samples, while in vibration laboratories, the values measured were vibration generated by the laboratory itself as well as its time-domain and frequency-domain parameters. A preliminary scheme was proposed for comparison test of vibration laboratories, which included sample design, test items and conditions, comparison test organizing, and comparison parameter processing. Conclusion Laboratory comparison test could be applied to vibration laboratories, and is important for evaluating the capability of a vibration laboratory and also the capability distribution of multiple laboratories. |
