一、叠加式力标准机负荷波动性的来源分析根据JJG1116-2015《叠加式力标准机检定规程》的要求,0.03级、0.05级、0.1级的叠加式力标准机的30S负荷波动性要求分别为0.01%、0.02%、0.03%。在实际工作中,标准机计量检定人员常用的标准测力仪,其测量仪表为DMP40,灵敏度值通常为2.00000m V/V,其0.01%即20个变动的数字量;0.02%即40个变动的数字 First, the superimposed force standard machine load fluctuation source analysis According to JJG1116-2015 “superimposed force standard machine verification procedures” requirements, 0.03, 0.05, 0.1 level superposition force standard 30S load fluctuation requirements 0.01%, 0.02%, 0.03%. In practical work, the standard dynamometer used by standard machine verification testers is DMP40. The sensitivity value is usually 2.00000m V / V, 0.01% of which is the number of 20 changes; 0.02% or 40 changes The number of
