摘　　要：随机振动和正弦振动是常见的振动试验.在试验结束后给出试验结果,完整的试验结果应包括不确定度评定。本文根据随机振动、正弦振动试验过程中产生的数据,对表征试验结果的关键参数进行不确定度评定,从而完整的表示试验结果的可信程度。Random vibration and sine vibration are common vibration tests.After the tests,the results need to be provided.The complete test result should include an evaluation of uncertainty.This article evaluates the uncertainty of key parameters that characterize the test results based on the data generated during random vibration and sine vibration tests,in order to fully represent the credibility of the test results.

关 键 词：不确定度 随机振动 正弦振动
