The analysis of CG measuring machine using Gauge Repeatability and Reproducibility

Abstract

The Center of Gravity (CG) is a significant parameter for military vehicles such as launching and amphibious vehicles. This paper presented the approach to evaluate the reliability of the CG measuring machine. The value of accuracy and uncertain of the machine was demonstrated by using Gauge Repeatability and Reproducibility (GR&R) method that repeatedly compares the value of the whole weight with the CG position of vehicle. The measured data, providing the official standard information, was compared with the commercial vehicle. The experimental results were verified the reliability of repeatability and reproducibility of the CG finding machine with acceptant value
