- Abstract:
- This research deals with a weighing system used under the conditions in which various movements exist. These various movements are heaving motion, rolling motion, pitching motion, etc. In this paper, these various movements are collectively called as "vibration-like movements". The term of "vibration-like moving conditions" means the conditions in which vibration-like movements exist. In a previous paper, the weighing system which has 3 dummy loadcells is discussed. "Dummy loadcell" is the loadcell which observes the vibration-like movements. We manufactured the weighing system and made several experiments with the weighing system. As a result of those experiments, it is confirmed that the proposed method is able to weigh under the vibration-like moving conditions accurately.
The purpose of this research is the practical realization of the weighing system. In order to put the weighing system into practical use, it is needed to reduce the size and weight of the weighing system. Accelerometers are substituted for the dummy loadcells. Generally, accelerometers are lighter and smaller than loadcells. This research verifies the effectiveness of the weighing system with "dummy accelerometers". - Keywords:
