一、现力值的测量不确定度影响因素按照结构分析可以得出各类型力标准机的主要不确定度影响因素以及影响的途径和程度。静重式力标准机的主要影响因素包括砝码质量、重力加速度、空气密度、砝码密度等参数的测量不确定度,同时还受工作台水平度(或拉头同轴度)、砝码摆动量等的影响。杠杆式力标准机的主要影响因素除静重式力标准机的影响因素之外,还包括杠杆放大比、杠杆灵敏阈等的影响。液压式力标准机的主要影响因素除静重式力标 First, the current value of the measurement uncertainty of the influencing factors According to the structural analysis can be drawn on all types of force standard machine the main factors affecting the impact and uncertainty of the ways and degrees. The main influencing factors of the static weight force standard machine include the measurement uncertainty of weight quality, gravity acceleration, air density, weight density and other parameters, as well as the level of the worktable (or the coaxiality of the slider), the weight The amount of swing and other effects. Lever force standard machine main factors in addition to static heavy force standard machine factors, but also include the lever amplification ratio, lever sensitivity threshold and so on. Hydraulic force standard machine in addition to the main factors of static heavy force standard
