随机振动试验系统测量结果不确定度评定

The Estimate of Indeterminacy of Metrical Result of Random Vibrational Testing System

结合军工产品随机振动试验工作实际,根据检定规程JJG948-1999数字式电动振动试验系统的要求,提出对随机振动试验系统测量结果的不确定度评定方法,并进行测量、评定和计算,并给出随机振动试验系统的合成标准不确定度和扩展不确定度。使随机振动试验系统测量结果更科学合理可靠。

Base on the fact of the random vibrational test of war industry production and the demand of regulation JJG948-1999 testing system of digital dynarnoelectnc hbration. The estimatmg method of metrical result s mdeterminacy of random vibrational testing system is estimated in this paper, and the all indeterminacy are measured,estimated and accounted.The compound indeterminacy and extended indeterminacy of random vibrational testing system are presented,so the metrical result is more scientific and credible.
