Abstract

The Monte Carlo simulation (MCS) method and the Guide to the Expression of Uncertainty in Measurement (GUM) are the most widely used approaches for uncertainty estimation. In this paper, MCS and GUM were used to estimate the confidence of MOI measurement equipment developed in-house. According to the results, the GUM estimated uncertainty was slightly underestimated compared to the MCS method. This difference is due to the approximation used by GUM. MOI uncertainties estimated by both methods were less than 1% of the estimate, which shows the high measurement reliability of the developed MOI measurement system.

몬테카를로 시뮬레이션 방법과 측정불확도 표현 지침은 불확도 평가를 위해 가장 널리 사용되는 방법들이다. 본 논문에서는 자체 개발된 질량관성모멘트 측정장비의 신뢰도를 평가하기 위해 몬테카를로 방법과 GUM방법이 사용되었다. 결과에 따르면 GUM방법에 의해 평가된 불확도가 몬테카를로 방법에 의한 것보다 약간 과소평가되었고 그 차이는 GUM방법의 근사화에 기인한 것으로, 두 방법에 의해 평가된 관성모멘트 불확도들은 추정량의 1% 미만으로 개발된 관성모멘트 측정시스템의 높은 측정신뢰성을 보여준다.
