High accurate weighing system used under the vibration-like moving conditions - on estimation of angular velocities

This paper describes a method for high accurate mass measurement under vibration, like moving conditions. In the previous paper, numerical simulations and experiments with a simple experimental apparatus demonstrated the effectiveness of the mass measuring method proposed by the authors. It is also confirmed that the influence of vibration-like movement depends on the position of the gravity center of the weighed object. As a step for a practical application, the development of the weighing system with 3 dummy loadcells is important. The weighing system to be treated in this paper consists of a weighing loadcell and 3 dummy loadcells. The simulated and experimental results with the trial-manufactured weighing system are reported. The estimating method of angular velocities is also explained. The effectiveness of the proposed measuring method is clarified both by the simulation and fundamental experiment.
