振动实验室比对探讨

Discussion on Vibration Laboratory Comparison

目的把实验室比对应用到振动实验室。方法参考测量实验室比对的成熟方法,分析振动环境试验的特点及其与普通测量试验比对的区别。结果指出一般的测试实验室被测量是样品的客观属性,但是振动实验室的被测量由各实验室自己产生的振动及其时域频域属性。提出了振动实验室开展比对的初步方案,包括样品设计、试验项目和条件、比对试验组织、比对参数处理等。结论实验室比可以用于振动实验室,对评价振动实验室能力、评价多个振动实验室能力分布有重要作用。

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.
