Force transducers have prominently been utilized in numerous scientific, industrial and metrological applications since decades. They have been developed for the measurement of force in lower as well as the higher capacity to fulfil the industrial and technological requirements. Generally, a force transducer is calibrated as per standard process. For the better perceptive, there is a need of well defined calibration procedure in an organized structure according to standard ISO 376-2011. Also, factors affecting the uncertainty of measurement using law of propagation (LPU) method and their analysis have been discussed. The relative uncertainty contributions due to different factors have been explained with suitable mathematical expression. An alternative approach for evaluating uncertainty of measurement is Monte Carlo Simulation Method (MCS) that assigns probability distribution function (PDF) to input quantities and output. Efforts have been accomplished to determine uncertainty of measurement of force transducer using both methods.

蒙特卡罗仿真在力传感器测量不确定度评估中的实现

几十年来，力传感器已在众多科学，工业和计量应用中得到了广泛应用。它们是为满足工业和技术要求而以较低和较高的能力进行测量而开发的。通常，力传感器按照标准过程进行校准。为了更好地感知，需要根据标准ISO 376-2011在组织结构中定义明确的校准程序。此外，还讨论了影响使用传播定律（LPU）方法进行测量不确定性的因素及其分析。已经用合适的数学表达式解释了由不同因素引起的相对不确定性贡献。评估测量不确定度的另一种方法是蒙特卡洛模拟方法（MCS），该方法将概率分布函数（PDF）分配给输入量和输出。已经完成了使用两种方法来确定力传感器的测量不确定性的努力。
