This paper describes a new method for high accurate mass measurement under vibration-like moving conditions. Although there exist research works on the mass measurement under vibration-like moving conditions, the effect of mass center of the weighed object is not taken into account in these researches. However, the influence of vibration-like movement, e.g. heaving, pitching, rolling, swinging, etc., on the measured value depends on the position of mass center of the weighed object. Therefore, the measured value obtained only by using the information of the vibration-like movement may not show sufficient accuracy. The authors propose a new method that measures a mass value considering both the information of vibration-like movement and that of the position of mass center of the weighed object. A mass measuring system to be treated in this paper consists of the weighing loadcell and several dummy loadcells, that are installed for getting the information both of the position of mass center of the weighed object and of vibration-like moving conditions. The effectiveness of the proposed measuring method is verified both by simulation and by a fundamental experiment.
